Arecipe for banana bread spread requires 3 cups of bananas for every 1 1/2 cups of sugar used. at this rate, how many cups should be used if 2 cups of banana are used?

We need 1 cup of sugar for 2 cups of bananas

Step-by-step explanation:

We can use proportions to solve this problem.  Put bananas on the top and sugar on the bottom

3 cups              2 cups bananas

=

1 1/2 cups      x cups sugar

Using cross products

3 *x = 2 *  1 1/2

Changing to decimals

3x = 2* 1.5

3x = 3

Divide by 3

3x/3 = 3/3

x=1

We need 1 cup of sugar for 2 cups of bananas

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
