Answer:
x=-1, y=-3. (-1, -3).
Step-by-step explanation:
-6x+4y=-6
-8x+4y=-4
------------------
-6x+4y=-6
-(-8x+4y)=-(-4)
----------------------
-6x+4y=-6
8x-4y=4
--------------------
2x=-2
x=-2/2
x=-1
-8(-1)+4y=-4
8+4y=-4
4y=-4-8
4y=-12
y=-12/4
y=-3
That's point-slope form:
y - y1 = m(x - x1)
Where y1 is the y-value of a point on the line, x1 is the x-value, and 'm' is the slope.
So let's find out what goes in the first blank.
As we can see, they replaced 'x1' with -1, and one of our points have an x-value of -1, that point is (-1, -2), this means y2 must be -2:
y + 2 = m(x + 1)
Now let's find the slope between the two points.
m = y2-y1/x2-x1
m = (10+2)/(3+1)
m = 12/4
m = 3
So the slope is 3, plug that in:
y + 2 = 3(x + 1)
