Answer:
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
Answer:
B
Step-by-step explanation:
It's not going negative you can tell by the line it has y-intercept and the last on didn't the other ones have aa negative. If you have a problem with these kinds of equations just do process of elimination and you'll be fine also here's the answer to another question
