Answer:
b no
Step-by-step explanation:
c^2 =![\sqrt{a {}^{2} +b {}^{2}} 9 + 25 \: is \: not =81](https://tex.z-dn.net/?f=%20%5Csqrt%7Ba%20%7B%7D%5E%7B2%7D%20%20%2Bb%20%7B%7D%5E%7B2%7D%7D%20%3C%2Fp%3E%3Cp%3E9%20%2B%2025%20%5C%3A%20is%20%5C%3A%20not%20%20%3D81)
We can use the points (-4, -1) and (-8, 7) to solve.
Slope formula: y2-y1/x2-x1
= 7-(-1)/-8-(-4)
= 8/-4
= -2
Find the y-intercept.
y = 2x + b
-1 = 2(-4) + b
-1 = -8 + b
-1 + 8 = -8 + b + 8
7 = b
Now, put in slope-intercept form.
y = -2x + 7
Hope This Helped! Good Luck!
