My apologies for the mistake. Let's calculate the slope and y-intercept first.
From the table:
(0, 0) and (1, 1) are two points on the line.
Slope (m) = (y2 - y1) / (x2 - x1)
m = (1 - 0) / (1 - 0)
m = 1 / 1
m = 1
Now that we have the slope, we can substitute one of the points into the slope-intercept form equation to find the y-intercept (b).
Using the point (1, 1):
1 = 1(1) + b
1 = 1 + b
b = 0
So, the equation in slope-intercept form is:
y = x + 0
y = x
From the table:
(0, 0) and (1, 1) are two points on the line.
Slope (m) = (y2 - y1) / (x2 - x1)
m = (1 - 0) / (1 - 0)
m = 1 / 1
m = 1
Now that we have the slope, we can substitute one of the points into the slope-intercept form equation to find the y-intercept (b).
Using the point (1, 1):
1 = 1(1) + b
1 = 1 + b
b = 0
So, the equation in slope-intercept form is:
y = x + 0
y = x
