Answer:
y = 4x + -9
Step-by-step explanation:
The y intercept which is -9, is the point in which the graph crosses the x-axis
In order to find the slope we need to identify two clear points on the graph.
- (0, -9)
- ( 1, -5)
Now that we have our two points we need to find the distance between them.
As you can see on the attachment the distance between the two points is 4 units up and 1 unit to the right, therefore the slope is 4/1 = 4.
Final Answer: y = 4x + -9
The <u>Distance Formula</u> = 
A(1,1) ⇒ the first 1 is
& the second 1 is 
.
B(7,-7) ⇒ the first 7 is
& the second is -7 is 
.
Now all you have to do is SUBSTITUTE the variables into the distance formula to get:
.
After you plug that formula into your graphing calculator (or solve it manually & mentally), you should end up with the answer 10, therefore d=10.
