Answer:
Slope is equal to the change in y over the change in x , or rise over run.
m=change in y/ change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m=y2−y1/x2−x1
Substitute in the values of x and y into the equation to find the slope.
m=0−(2)/9−(5)
Simplify.
m=−12

Answer:
Y=4x+4 is y4 and x 1 on the graph and 1x and 1y
Y= 4x+2 is 2x 0y and 6x and 1x 6y
Step-by-step explanation:
Answer:
41
Step-by-step explanation:
Given
(7 + 2
)(7 - 2 ) ← expand factors using FOIL
= 7² - 2 + 2 - (2 )² ← collect like terms
= 49 - 8
= 41
