Answer:
A is the cheapest deal.
Step-by-step explanation:
find unit rate; cost / quantity
20.20 / 10 = $2.02 per gallon
26.04 / 12 = $2.17 per gallon
28.24 / 24 = $2.01 per gallon
30.45 / 25 = $2.03 per gallon
Number the answer is 4.5 as the slope and -2 as the y-intercept and number 10 the slope is -1 and the y-intercept is 1
Answer:
y-4=-5/4(x-(-4))
Step-by-step explanation:
Slope form is y-y1=m(x-x1)
X1and Y1 are a point on the line and M is the slope
THE SLOPE IS -2
if we have the coordinates of two points on a line, we can find the slope with this formula:

so the slope is

the answer is -2
good luck
