135 think of if you had 90 dollars and you increased it by 50% you would then have $135
The equation that shows the relationship between x and y is:
y = 5x
A linear equation is in the form:
y = mx + b
where m is the rate of change and b is the initial value of y, y, x are variables.
Let x represent the number of nights knitting and y represent the length of the scarf.

To find the x intercept, sub in 0 for y and solve for x
2x - 5y = 20
2x - 5(0) = 20
2x = 20
x = 20/2
x = 10....x intercept is (10,0)
to find the y intercept, sub in 0 for x and solve for y
2x - 5y = 20
2(0) - 5y = 20
-5y = 20
y = -20/5
y = -4....y intercept is (0,-4)
Answer:
-10 and 2
Step-by-step explanation:
1. Think about what numbers multiply to -20: -10 and 2, 10 and -2, -20 and 1, 20 and -1, 4 and -5, -4 and 5
2. Then, think about which of the above adds to -8. This leaves you with -10 and 2
