Answer:
slope=2
Step-by-step explanation:
subrtract -4-(-4) the two negatives make it a + so that becomes 8 and thats for the top one the bottom is 6-2 which is 4 then divide 8 by 4 to find the slope which is 2.
For x=5 y=4 so we can calculate the slope m=(y1-y)/(x1-x)=(5-0)/(4-0)=5/4
then use (y-y1)=m(x-x1) and you get
y=(5/4)x-5
7^-2= 1/7^2
= 1/14
= 0.071429
