y=-5x-3

Explanation:

When given a set of points and the slope, use the point slope formula, which is:

y-y_1=m(x-x_1)

Where y_1 is the y in the set of points
x_1 is the x in the set of points
And m is the slope

Plug in the numbers into the equation

y+3=-5(x-0)

Distribute the -5 throughout the set of parenthesis

#y+3=-5x+0

Subtract 3 on both sides of the equation

y=-5x-3
