How to solve 9x-7y=-7

Mathematics
1 answer:
frutty [35]3 years ago
7 0

first lets solve for x
9x-7y=-7
it will be easier to start if the equation is equal to 0
so first add 7 on both sides
9x-7y=-7
+7      +7
now we have
9x-7y+7=0
now to get x on one side subtract 9x from both sides
<span>  9x-7y+7=0
</span>-9x           -9x
--------------------
-7y+7=-9x
now to get x alone we divide both sides by -9
7/9y-7/9=x

Hi guys can someone please help me with these questions please
Zinaida [17]

Hi There!

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

Question 2:

Obviously the right equation for this question is Point Slope Form.

Point Slope Form: y - y1 = m(x - x1)

y1 = -1

x1 = 3

m = 2

Question 2 Answer: y + 1 = 2(x - 3)

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

Question 3:

Again use point slope form.

Find Slope:

7 - 1 = 6

-2 - 1 = -3

6/-3 = -2

Question 3 Answer: y - 1 = -2(x - 1)

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

Hope This Helps :)
