Write an equation of the line with a slope of -3 and y-intercept of 0
klemol [59]

Answer:

y=-3x

Step-by-step explanation:

Slope intercept form is written as y=mx+b, where:

m= slope

b= y-intercept

We know the slope and y intercept already, so simply plug them in:

y=-3x+0

We can remove the +0 because it is redundant, therefore the final answer is:

y=-3x
