SORRY if its too late.
Proportions with variables:
let's look at an example from my homework hehe
.3:4=9:y
First, you change the ratios to fractions.
.3/4=9/y.
4 times 9 is 36. I multiplied the numerator of 9/y and the denominator of .3/4.
You also do this with the other numerators and denominators. .3 times y= 36. (Both equations have to equal the same number) if you don't know the answer, just do 36 divided by .3. The answer is 120.
y=120
The +1 in parenthesis is adding one to the x value, which shifts the graph 1 unit to the left, called a horizontal translation.
The 3 outside of the parenthesis is multiplying the X value by 3, which narrows the shape of the graph ( makes the curve 3 times sharper), which is called a vertical stretch.
Answer:
3.14%, increase i m sure if it is wrong its 1.12%, increase

Answer:
Step-by-step explanation:
Slope m = 1
Point (1;8)
x1 = 1 and y1 = 8
y - y1 = m(x - x1)
y - 8 = 1(x - 1)
y - 8 = x - 1
y = x - 1 + 8
y = x + 7
