What us the slope of the equation y - 5= -3x
adelina 88 [10]

Answer:

The slope is -3

Step-by-step explanation:

y - 5 = -3x

Slope-intercept form is y=mx+b

m = slope

b = y-intercept

To convert to slope-intercept form, add 5 to both sides.

This eliminates the 5 on the left side of the equation and isolates the y.

y - 5 = -3x

 + 5     + 5

Slope-intercept form:

y = -3x + 5

The slope is -3
