An equation for a line in the xy-plane allows you to find the value of y, given x. a. true b. false

An equation for a line in the xy-plane allows you to find the value of y, given x

the statement is true

here we are given with the value of x

so we have here two variables available

now it is a fact that if value of a variable is known in a equation we can easily get the value of other variable

here value of x is given which is a variable so it is evident that for a line in the xy-plane allows us to find the value of y, given x.

An equation in xy-plane will always have two variable x and y.

So if any one of x or y value is given then we can use that to find other x or y value.

Hence given statement is TRUE.

if x = 1, then the answer is 3.5
