13x - 4(2x - 5) = 15

Simplify.

13x - 8x + 20 = 15

Subtract 20 from both sides.

13x - 8x = 15 - 20

Simplify.

5x = -5

Divide both sides by 5.

x = -1

Find the graph of y=-3/4X-2

morpeh [17]

To graph the line $y=- \frac{3}{4}x-2$ we are going to take advantage of the fact that its y-intercept is -2 when x=0, so our first point is (0,-2). To find our second point, we are going to find the x-intercept; to do it, we are going to set y=0 and solve for x:
$y=- \frac{3}{4}x-2$
$0=- \frac{3}{4}x-2$
$2=- \frac{3}{4}x$
$x= \frac{2}{- \frac{3}{4} }$
$x=- \frac{8}{3}$
Now that we have our second point $(0,- \frac{8}{3} )$ , we just need to join our two points with a straight line.

We can conclude that the graph of <span>y=-3/4X-2 is:</span>
