Question

What is the equation of a line with a slope of -3 and a y-intercept of 4?

Answer 1

y = -3x+4

Explanation:

the equation of a line is: y = mx+b

Where:

m is the slope, and

b is the y-intercept

Replace m with -3 and replace b with 4, in the equation y=mx+b.

`m = -3\\b =4\\\\y =mx+b\\\\y =-3x+4`
