For this you want to put it into slope-intercept form: y=mx+b

-3x-4y=-12
add over -3x
-4y=3x-12
divide by -4
y=-3/4x + 3 (now it's in the right form!)

The slope is m (-3/4)
and the y intercept is b (3)

In form
ax+by=c
slope=-a/b
y intercpept=c/b

so

-3x-4y=-12
a=-3
b=-4
c=-12
slope=-(-3)/-4=3/-4=-3/4
yint=-12/-4=3

slope=-3/4
yint is 3

Answer:

y =-5x-17

Step-by-step explanation:

Slode-intercept is

y = mx + c

The first step is to find the slope, that is the m

To do that, use this formula

Y2 - y1

------------

X2- x1

And u will get - 5

Now since u got m, u also actually have y and x, those are the coordinates they gave u. U can choose either one,(-3, - 2) or (-4, 3), cuz they would give u the same answrs

So let's say I chose (-4, 3)

So x = - 4, y = 3

y=mx +c

3= - 5(-4) +c

C = - 17

Therefore your end product will be

y = - 5x - 17
