To find the equation of the line in slope-intercept form, we need to determine the slope (m) and the y-intercept (b).
To calculate the slope, we will use the formula:
m = (change in y) / (change in x)
The change in y = 8 - 4 = 4
The change in x = 1 - 0 = 1
So, the slope (m) = 4/1 = 4.
To calculate the y-intercept (b), we can use the point-slope form of the equation:
y = mx + b
We can substitute the values of one of the given points into the equation and solve for b.
Using the point (0, 4):
4 = 4(0) + b
4 = b
Therefore, the y-intercept (b) is 4.
The equation of the line in slope-intercept form is:
y = 4x + 4.

To find the equation of the line in slope-intercept form, we need to determine the slope (m) and the y-intercept (b).
To calculate the slope, we will use the formula:
m = (change in y) / (change in x)
The change in y = -1 - 2 = -3
The change in x = 1 - 0 = 1
So, the slope (m) = -3/1 = -3.
To calculate the y-intercept (b), we can use the point-slope form of the equation:
y = mx + b
We can substitute the values of one of the given points into the equation and solve for b.
Using the point (0, 2):
2 = -3(0) + b
2 = b
Therefore, the y-intercept (b) is 2.
The equation of the line in slope-intercept form is:
y = -3x + 2.
To calculate the slope, we will use the formula:
m = (change in y) / (change in x)
The change in y = -1 - 2 = -3
The change in x = 1 - 0 = 1
So, the slope (m) = -3/1 = -3.
To calculate the y-intercept (b), we can use the point-slope form of the equation:
y = mx + b
We can substitute the values of one of the given points into the equation and solve for b.
Using the point (0, 2):
2 = -3(0) + b
2 = b
Therefore, the y-intercept (b) is 2.
The equation of the line in slope-intercept form is:
y = -3x + 2.

To find the equation of the line in slope-intercept form, we need to determine the slope (m) and the y-intercept (b).
To calculate the slope, we will use the formula:
m = (change in y) / (change in x)
The change in y = 0 - (-2) = 2
The change in x = 3 - 0 = 3
So, the slope (m) = 2/3.
To calculate the y-intercept (b), we can use the point-slope form of the equation:
y = mx + b
We can substitute the values of one of the given points into the equation and solve for b.
Using the point (0, -2):
-2 = (2/3)(0) + b
-2 = b
Therefore, the y-intercept (b) is -2.
The equation of the line in slope-intercept form is:
y = (2/3)x - 2.
To calculate the slope, we will use the formula:
m = (change in y) / (change in x)
The change in y = 0 - (-2) = 2
The change in x = 3 - 0 = 3
So, the slope (m) = 2/3.
To calculate the y-intercept (b), we can use the point-slope form of the equation:
y = mx + b
We can substitute the values of one of the given points into the equation and solve for b.
Using the point (0, -2):
-2 = (2/3)(0) + b
-2 = b
Therefore, the y-intercept (b) is -2.
The equation of the line in slope-intercept form is:
y = (2/3)x - 2.

To find the equation of the line in slope-intercept form, we need to determine the slope (m) and the y-intercept (b).
To calculate the slope, we will use the formula:
m = (change in y) / (change in x)
The change in y = -1 - (-4) = 3
The change in x = 1 - 0 = 1
So, the slope (m) = 3/1 = 3.
To calculate the y-intercept (b), we can use the point-slope form of the equation:
y = mx + b
We can substitute the values of one of the given points into the equation and solve for b.
Using the point (0, -4):
-4 = 3(0) + b
-4 = b
Therefore, the y-intercept (b) is -4.
The equation of the line in slope-intercept form is:
y = 3x - 4.
To calculate the slope, we will use the formula:
m = (change in y) / (change in x)
The change in y = -1 - (-4) = 3
The change in x = 1 - 0 = 1
So, the slope (m) = 3/1 = 3.
To calculate the y-intercept (b), we can use the point-slope form of the equation:
y = mx + b
We can substitute the values of one of the given points into the equation and solve for b.
Using the point (0, -4):
-4 = 3(0) + b
-4 = b
Therefore, the y-intercept (b) is -4.
The equation of the line in slope-intercept form is:
y = 3x - 4.
