Graph the linear equation to -2x+7y=-21
2 answers:
Answer:
This equation is in standard form, so to make graphing easier you need to put it in y=mx+b form or slope, intercept form.
Step-by-step explanation:
I have attached a photo of what the graph would look like.
However, in the future you should know how to turn this into a slope intercept equation.
-2x+7y=-21
+2x +2x
7y=2x-21
divide the entire equation by 7
y= 2/7x-3
That is a full equation in slope intercept form.

We have to find x and x is the hypotenuse. We use this formula:
hyp²=side²+side²
So:
hyp²=side²+side²
hyp²= 12²+9²
hyp²= 225
hyp²= √225
hyp= 15
Therefore, the hypotenuse is 15 and x is 15.
