Can yall please help???

Question

Determine whether each equation is a lineasr equation. If so write the equation in standard form.

1) a + 1/5 b = 2
2) x/4 - y/3 = 1
3) 5/x - 2/y = 7

Answer 1

liner equation are lines lines must be able to be expressed in a equation such as y=mx+b. So as long as you can get it solved in that form its liner.

1.liner b=5a+10
2.liner y=-3/4x+3
3.not liner

Answer 2

Firstly, you meant to say write the linear equation among the 3 given in the y-intercept form, which is y = mx + b.

A linear equation is one that will produce a straight line when graphed. The word linear comes from the word LINE.

Okay?

I will one do one of these.

Follow my steps to solve the other two.

Got it?

I selected number 3.

(5/x) - (2/y) = 7

First thing to do: multiply by LCD to do away with the fractions.

Our LCD is xy read "x times y."

We multiply the LCD by each term.

We get:

5y - 2x = 7xy

If I isolate y on one side of the equation, the equation will not be in y-intercept form.

So, equation 3 is NOT linear.
