Write the equation of a line with a slope of 4 and a y-intercept of - 3

Y = 4x - 3

The formula for a line is y = mx + b, where m is the slope and b is the y-intercept. When you get a question such as the one you asked, simply plug in the numbers with the corresponding values and you will have your equation.

slope-intercept form:

y=mx+b

m=slope

b=y-intercept

dа ta:

m=4

b=-3

Then:

y=mx+b

y=4x-3

answer: y=4x-3
