Write an equation of the line with a slope of −3 and y-intercept of 0.

Answer 1

Nevaeh,

The slope-intercept equation of a line is:

y = mx + b where m is the slope, b is the y-intercept.

You're told the slope is -3, so go into the previous equation and replace m by -3.

You're told the y-intercept is 0, so go into the previous equation and replace b by 0.

Once you've replaced m and b, you'll have your answer :)
