3x - 2/5 = 8/5.

Let's combine the constants:  adding 2/5 to both sides of this equation yields  

3x = 10/5, or 3x = 2.

Solving for x:  x = 2/3

Find the slope of the line that passes through (-2, 8) and (-10, 14)
vesna_86 [32]
Hello!

To find the slope we divide the difference of the y-values by the difference of the x-values as shown below.

\frac{14-8}{-10+2} = -\frac{6}{8} = -\frac{3}{4}

The slope of our line is -3/4.

I hope this helps!
