The slope would be 0 because if you put in the coordinates with the formula, you would get the slope as 0. This also makes sense because both points have the same y point, so that means that the line wasn’t travelling up or down. And since it was only going through -8 that would be the y-intercept.
Answer:
y = 400x - 1200
Step-by-step explanation:
considering the linear equation y = mx + c
where y denotes number of items
x denotes item price
we have y = 2000 and x = $8 so we have now
2000 = m(8) + c ...... 1
now we have
y = 400 and x = $4
400 = m(4) + c .....2
from equation 1 and 2 we have
subtracting 2 from 1
1600 = 4m
m = 400
solving for c value
400 = 4m + c
400 = 4*400 + c
c = -1200
y = 400x - 1200
Answer:
14+28
Step-by-step explanation:
Amy bought 5 books for $0.50 and 7 for $.30, a total of 12
WORK
5 x .50 = 2.5
4.95 - 2.5 = 2.45
2.45 divided by .35 = 7
