Answer:
C, 2/5
Step-by-step explanation:
<u>.</u>
(X/3) - 8 = 12
X being a number divided by 3. This part in parentheses so you solve it first. Subtract 8 from that and your answer equals 12.
The formula is y=mx+b
To get the slope or m, use this formula
(the second y minus the first y)/(the second x minus the first x)
Now set it up.
(10-7)/(2--1)
3/3=slope is 1.
y=1x+b
Insert one of the points for x and y.
i will do (-1,7)
7=1(-1)+b
7=-1+b
8=b
Insert this into the final equation:
y=1x+8
Try it out. If you're not sure, try both points. If it works, then you set it up correctly.
