1. One is 2
2. Two is 2
3. Three is 4
4. Four is 3
Answer:
Select 1, 4 and 5
The slope is -1/10
The x intercept is 100
The y intercept shows the initial amount on the card in dollars
In order to vertically stretch a function by a factor k, we have to multiply the function expression by k.
So, in order to stretch the function by a factor of 1/5, we simply have to multiply:

So, if we shrink the function -5x by a factor of 1/5, we get the function -x.
Answer: 67
Step-by-step explanation:
Y=mx+b
m=slope
b=y intercept
we are given (3,-1)
one solution is x=3 and y=-1 or
when x=3 then y=-1
also slope=2
so
y=2x+b
subsitue 3 for x and -1 for y and solve for b
-1=2(3)+b
-1=6+b
subtract 6
-7=b
y=2x-7 is equation
answer is number 4
