M 7=280. you just multiply 7 by 40 to get your answer. i am pretty sure.
Answer:
y = 2.5x
Step-by-step explanation:
y = mx + b
m=2.5 (slope) --> y=2.5x+b
coordinate : (2,5) 2 is the x coordinate, 5 is the y coordinate
to Find b, input the coordinate --> 5 = 2.5(2) + b
5 = 5 + b
0=b
y= 2.5x
This is only since it asked to solve using the point. If you look at the graph, the line intercepts the y-axis at (0,0) so b=0.
hope this helps

What is the result of isolating y^2 in the equation below (x-2)^2+y^2=64?
Solution:
We want to isolate
from the equation 
To isolate
, we must try to get
alone
So, We must subtract
from both sides
