To find the equation of the line in slope-intercept form, we need to determine the slope (m) and the y-intercept (b).
First, let's calculate the slope using the formula:
m = (change in y) / (change in x)
Using the given points:
m = (-4 - (-3)) / (-8 - (-10))
m = (-4 + 3) / (-8 + 10)
m = -1 / 2
Now that we have the slope, we can use one of the points to find the y-intercept by substituting the values of (x, y) into the slope-intercept form equation: y = mx + b
Using the point (-10, -3):
-3 = (-1/2)(-10) + b
-3 = 5 + b
b = -8
With the values of m = -1/2 and b = -8, the equation of the line in fully simplified slope-intercept form is:
y = (-1/2)x - 8
Write the equation of the line in fully simplified slope-intercept form.
