A direct variation is a proportional equation. Such as:
For every 3 cookies, linda gets 1 glass of milk. The equation for this is y=3x where y is the glasses and x is the cookies. this is a direct variation. It also has a linear line. Linear means straight. Rate of change and slope are the exact same thing. They are the value of 'm' in y=mx+b
The answer is D) (-1,-12)
Reason:
1) substitute 2x-10 for y in y=4x-8
2) 2x-10=4x-8
3) -2x-10=-8
4) -2x=2
5) x=-1
6) substitute -1 for x in y=2x-10
7) y=(2)(-1)-10
8) y=-12
Answer
x=-1 and y=-12
Answer:
m= 2/3
Step-by-step explanation:
up 2 right 3
y= 2/3x-2
Answer:
D. 62.5
Step-by-step explanation:
2 ways
1.
7.5 ÷ 3 = 2.5
25 times 2.5 = 62.5
2.
3/7.5 = 25/x
3x = 187.5
187.5 ÷ 3 = 62.5
The answer is A, hope this helps brooo
