Step-by-step explanation:
Answer:
-1.5,-1,0,0.5,1 is the answer
2 inches per minute. Just divide the total amount of inchs by the number of minutes and you have your unit rate.
Gg easy
point slope:
for opint (x1,y1) and slope m
y-y1=m(x-x1)
so example
(1,2) and slope 3
y-2=3(x-1)
slope intercept
y=mx+b
m=slope
b=y intercept
if slope is 2 and y intercept is 3
y=2x+3
standard form
Ax+By=C
easies of all, just put randome numbers
2x+3y=4
A=2
B=3
C=4
