Answer:
y=5x+29
Step-by-step explanation:
1. find slope
y2-y1/x2-x1
9--6/-4--7= 15/3=5
2. substitute x and y
(-4, 9)= 9=5(-4)+b
9=-20+b
29=b
3. put it together
y=5x+29
B is the answer hope I helped u out!!!

Answer:
Step-by-step explanation:
All we can do here is combine like terms (add those that have the same the same exponent)
Good luck!
Answer:
B
Step-by-step explanation:
First create the equation that has slope of -1 in the form of y=mx+b. Because the slope is -1, m=-1, so the equation is y=-x+b. Now we see that we are given the point (-3, 8) as an intersection point. Substitute x and y for -3 and 8 in our equation. With this information, our equation becomes 8=3+b. Solving, b=5. Our equation is now y=-x+5.
Simplifying all of the answer choices, we have
A. y=-x-5
B. y=-x+5
C. y=-x-5
D. and E. as what they already show
The only answer that matches is B.
