Five yards of material is needed to make
2 curtains. this represents a proportional
relationship. if the relationship (curtains,
material) were graphed, what would the
y-coordinate be if the x-coordinate was 7?
pmp

The y-coordinate would be 17.5

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

y ----->material needed in yards

x ----> number of curtains

we know that

For y=5, x=2

Find the value of the constant of proportionality k

substitute the given values of x and y

The linear equation is equal to

If the x-coordinate was 7

then

substitute in the equation x=7 and solve for y

therefore

The y-coordinate would be 17.5

care to share were the trapezoid shown is ?

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
