The fraction a/b must be equal to which expression a b+a
b b divided by a
c a + b
d a divided by b

I.e , a/b

Well, a fraction is essentially a division expression. So A and C are out because those are addition expressions.

B and D are left. Because a is being divided by b, instead of b divided by a, the only answer left would be D.

sorry if this doesn't help

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
