Find the slope of the line represented by the table of values.
a)
1
2
b) 1
c) 2
d) 4

The slope is the change in Y over the change in X.

Using any two of the X and Y values solve for the slope:

Using the first and last value:

(-1,1) and (7,5)

Slope = (5-1) / (7 - -1)

Slope = 4/8

Slope = 1/2

c. 4 1/4 pounds

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
