Question

what is the equation of a line that has a slope of 3 and a y-intercept of -3

Answer 1

Answer:

y = 3x-3

Step-by-step explanation:

y = mx+b

m is your slope and b is your y-intercept

plug those numbers in

y = 3x-3

Answer 2

The slope-intercept form:

y = mx + b

m - slope

b - y-intercept

We have m = 3 and b = -3. Substitute:

y = 3x - 3
