X = 4

-2x - 4 + 5x = 8

Add up the X’s: 3x - 4 = 8

Isolate the X’s, Transfer -4 to the other side of the equal sign, while also flipping the sign (negative & positive): 3x = 8 + 4

Add up the 8 & 4: 3x = 12

Divide each side by 3: 3x/3 = 12/3

Final Answer: x = 4

I recommend using Photomath as it scans math problems, solves them, and shows you how it is done. It’s quite helpful.

Which graph represents a line with a slope of -2/3

sertanlavr [38]

Answer:

$y=-\frac{2}{3} x-2$

Step-by-step explanation:

the general equation for a line is:

$y=mx+b$

where $m$ is the slope of the line, and $b$ is the y-intercept.

Since we need a slope of -2/3:

$m=-\frac{2}{3}$ ,

So far we have that the line must have the equation:

$y=-\frac{2}{3} x+b$

the graph of a line with a negative slope is one that "falls" from left to right in the plane. And the number $\frac{2}{3}$ means that it falls at a ratio of 2 units in the y-axis for every 3 in the x-axis.
