Question

A line has a slope of -3 and passes through the point (5,-1). what is the equation of the line?

Answer 1

y = -3x

Explanation:

the equation of the line would follow the formula y = mx + b, where m is the slope and b is the y-intercept. the slope is -3 so we would substitute that in for m. and since there is no y-intercept in this situation, our equation would be y = -3x.

i hope this helps :)
