Write an equation in point-slope form of the line that passes through the point (1,-3) with slope 4

Question

y-____=_____(x-___)

8th grade math

Answer 1

slope = m = 4

general equation for a line in slope intercept form is

y=mx + b where m is slope and b= y intercept

y=4x+b. Plug in the point (1,-3) to calculate b

-3 = 4(1) + b

b = -3-4= -7

y= 4x -7 is the line with slope 4 and going through the point (1,-3)
