Question

Write the equation of the line that passes through (3, 6) and (0, –3) in slope-intercept form.

a. y = 3x – 6

b. y = 3x – 3

c. y = 3x + 3

d. y = 3x + 6

Answer 1

b.

Answer 2

To find your slope you will use the equation: \[m=\frac{y_2-y_1}{x_2-x_1}\] and you can then put your equation into point-slope form, \((y-y_1)=m(x-x_1)\), and rearrange it into slope-intercept form to get your answer.
