Question

Write the equation of the line that has a y-value that increases by 4 for every x that increases by 1. It also crosses the y-axis at –2.

Answer 1

The slope intercept form of a line is given by y = mx + c.
m = increase in y / increase in x
c = y-intercept/the y value when the line cuts the y-axis.
