Question

Find the equation of a line which has:

slope of -2 and
crosses the y-axis at 5

in slope-intercept form

Answer 1

y = -2x + 5

Explanation:

Recall that slope-intercept form is y = mx + b where m is the slope and b is the y intercept

In this case our slope is m = -2

and, line crosses y-axis at 5 which is b = 5

thus, y = -2x + 5
