Question

matttthhhh , i need help


What is the equation, in slope-intercept form, of the line that passes through (0, −2) and has a slope of −3?

a. y = −3x − 2
b. y = −3x + 2
c. y = −2x + 3
d. y = −2x − 3

Answer 1

Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. We are given the slope of -3, but we need the y-intercept. We will sub in the x coordinate for x in the equation and the y coordinate for y in the equation, along with the slope and solve for b. -2 = -3(0) + b and -2 = b. Rewriting the equation, we have y = -3x - 2.
