-4x+-6y=24 how do you solve?

alina1380 [7]

So,

Let's manipulate this into the y=mx + b form.

Add 4x to both sides
-6y = 4x + 24

Divide both sides by -6
$y = \frac{4}{-6} x - 4$

Just use the slope to find the points you need.

The y-intercept is (0,-4).

The slope is $\frac{4}{-6}$ . Finding the next point:
(-6,0)

You could have also used the <em>slope intercept method.</em>

-4(0) - 6y = 24
-6y = 24

Divide both sides by -6
y = -4
(0,-4)

-4x - 6(0) = 24
-4x = 24

Divide both sides by -4
x = -6
(-6,0)
