Question

what is the equation in point-slope form of the line that passes through the point (1,-1) and has a slope of 4?

Answer 1

Explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

`y - y_1 = m(x - x_1)`

where

m is the slope

( x1 , y1) is the point

From the question the point is (1,-1) and the slope is 4

The equation of the line is

`y + 1 = 4(x - 1)`

Hope this helps you
