If I could see the graph correctly, then the y-intercept should be -5.

First I’ll write down the points given (-4,5),(-1,-7.5)
Second, I will find the slope, and the slope formula is y2-y1/x2-x1
Third, I’ll plug in the points into the formula -7.5-5/-1-(-4) = -12.5/3= -37.5
Fourth, you could plug in the points in slope intercept form y=mx+b or point slope form y-y1=m(x-x1), I’ll use slope intercept form.
5=-37.5(-4)+b
5=150+b
-145=b
b=-145

So your answer will be -145.

Answer:

X= -1 and x=5

Explanation:

Make it equal to zero
X-5=0
Then add five to both sides
X=5
For the other one do the same
X+1=0
Then subtract one on both sides
X=-1

Meg has a can that contains 80% of orange juice and the rest water. The can has 1 liter of water.

ladessa [460]

Let O be the amount of orange juice and W be the amount of water.

A)
O = 0.8W

B)
W = 1, so:
O = 0.8(1)
O = 0.8 Liters
