Determine the slope and y-intercept of the graph:
7x + 4y = 28

slope is  (-7/4) and y-intercept is 7

Step-by-step explanation:

If we convert the equation 7x + 4y = 28  into Slope-intercept form, we can find the slope and the y-intercept.

7x + 4y - 7x  =  28  - 7x

4y =  28 - 7x

divide both sides by 4

y = (28 - 7x)/4

y = 7 - 7x/4

slope is  (-7/4) and y-intercept is 7

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
