What is the slope of y = -1 + 3x?

zubka84 [21]

Answer:

− 3

Step-by-step explanation:

We can rewrite the equation as: y = − 3 x + 0 This equation is now in the slope-intercept form. The slope-intercept form of a linear equation is: y = m x + b Where m is the slope and b is the y-intercept value. For: y = − 3 x + 0 the slope is: m = − 3
