Find two points on the graph and plug them into the formula.
(0,0) and (1,4) are the easiest.
(y2-y1)/(x2-x1)=m
(4-0)/(1-0)=m
4/1=1
m=4
Answer: -17
f(-2)= -2^2 + 4(-2) -5
-4 + (-8) -5
-4-8-5= -17
Answer:
5
Step-by-step explanation:
balls + sports towels = Total
(3 * 6) + (8x) = 65
18 + 8x = 65
8x = 47
x = 5.875
Cannot buy .875 of a towel so answer has to be rounded down to 5 towels.
Answer:
-7
Step-by-step explanation:
The slope formula is (y1 - y2) / (x1 - x2).
In this question we have two points: (1,5) and (2,-2).
x1 = 1
y1 = 5
x2 = 2
y2 = -2
then, plug in these numbers into the slope formula
(5-(-2))/(1-2) = 7 / -1 = -7
