Help help plz plz plz with 7and 8

6. 3, 2, -4

7. 4, -1, 4, -9

8. -1, 4, -25, 4

Step-by-step explanation:

Well if you need 7 and 8 I can give you 6 as well.

So #6 states that line EF has to be written in slope intercept which is

So we have to find the slope which is A and B and the y intercept which is C.

So the y intercept is the point on the y axis which is E. So E is -4.

So the y intercept is -4.

Now for the slope. We can find the slope by seeing how far each points are way from each other which is .

So our equation is y = 3/2x - 4.

So the values of ABC are 3, 2, and -4.

Now we have to do #7.

So #7 states GH needs to be written in point-slope form.

So in the question we have to find ABCD and the equation is So BC is the slope A is a y coordinate and D is a x coordinate. So to find the slope we do the same thing find how far away each points are from each other, so the slope is -1/4.

Now since this is point slope form we don’t need the y intercept but we do need the coordinations on one point.

We can use G which is (-9,4). So A is the y coordinate which is 4 and D is -9.

So the equation is .

So ABCD are 4, -1, 4, -9.

Time for the last one #8.

So #8 states GH needs to be written in slope intercept form.

And you might think that this will be long and boring but you can actually put slope-point form into slope intercept form by combining like terms, distribution, and putting y by itself.

So in point slope form it is and look at the image below to see how I got .

So ABCD is -1, 4, -25, 4.
