-5x+y=-3

1 answer:

5 0

(3)(-5x+y=-3)
(5)(3x-8y=24)

-15x+3y=-9
15x-40y=120

3y=-9
-40y=120

-37y=111
Divide both sides by -37

y=-3

To solve for x. Choose one equation from the given and plug what you get in Y.

I'll choose, -5x+y=-3
So, -5x+(-3)=-3
-5x=0
Divide both sides by -5
x=0/-5

Hope, this helps.

Answer:

The slope for this equation is $\frac{1}{7}$ .

Step-by-step explanation:

x y

point 1: -4 -3

point 2: 3 -2

slope: $\frac{1}{7}$

To solve for slope here is an equation, to help: $\frac{y^2-y^1}{x^2-x^1}$

$\frac{y^2-y^1}{x^2-x^1} \\\\\frac{-2-(-3)}{3-(-4)} \\\\= \frac{1}{7} \\$
