What is 9x-7y=-7 in slope intercept form?

1 answer:

4 0

Slope intercept form is y = mx + b

So if you start with 9x - 7y = -7, the first thing you need to do is move the 9x to the other side of the equation by subtracting it from both sides.
9x - 7y = -7
-9x -9x

Now you have -7y = -9x -7

For the equation to be in slope intercept form now you should divide every term by the number in front of your y. In this case divide every term by -7
-7y = -9x -7
-7 -7 -7

That leaves you with: y = 9x/7 + 1

Answer:

The answer is " $\frac{1}{25}$ "

Step-by-step explanation:

They might claim that perhaps the ratio to Raul would've been: $\frac{y}{x} = \frac{5}{125} = \frac{1}{25}$ per each 125(x) page, which he reviewed throughout a summer competition.

Raul's cost per unit for each paragraph reads is $\frac{1}{25}$ page points, that's why the model a link with the same unit rate. please find the graph in the attached file.
