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

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

Answer: y = - 3x + 0

Explanation: We can use the formula y = mx + b to write this equation. M = the slope, and b = the y-intercept. Let's plug our numbers in:

Y-intercept: 0

Slope: - 3

y = - 3x + 0
