To find the equation in slope-intercept form, we need to find the slope (m) and the y-intercept (b).
First, we can find the slope by using the formula:
m = (y2 - y1) / (x2 - x1)
Using the given points (-3, 0) and (-1, 6):
m = (6 - 0) / (-1 - (-3))
m = 6 / 2
m = 3
Now that we have the slope, we can use one of the given points to find the y-intercept:
Using the point (-1, 6) and the slope m = 3:
y = mx + b
6 = 3(-1) + b
6 = -3 + b
b = 9
Therefore, the equation in slope-intercept form is:
y = 3x + 9
