What is the slope of this line?

MrMuchimi

We can use the coordinates (-4, 5) and (0, 6) to find the slope.

Slope Formula: $\frac{y2-y1}{x2-x1}$

Solve: $\frac{6 - 5}{0 - (-4)} = \frac{1}{4}$

The slope of the line is \Large\boxed{\mathsf{1/4}}

Written in slope-intercept form: y = 1/4x + 6

Hope This Helped! Good Luck!
