A little help here ^_^

 I really am not very sure but 68 in square seems resonible

Step-by-step explanation: becuase If you multiply only one side of them altogether it gets you 315 letting you know its a greater awnser The highest is 88 though it would not be that high knowing these types of problems i went and took an estimite for 68 inches square Hope this helps !!!

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
