1.) Use the rectangular prism shown to answer questions a.) and b.)
a.) Find the surface area of the prism

Step-by-step explanation:

5 in, 3 in, 15 in

Referencing to width on most rectangular prisms, the smallest value is likely to be width. Which is crossed out to get from volume formula to surface area formula.

So from (5in)(3in)(15in) goes to (5in)(15in), multiplied, the surface area of the prism is 75

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

positive

step-by-step explanation:

the quadrant is facing upwards
