Question

How would you graph 4x-7y=28 ?

Answer 1

y = 4/7x - 4

Explanation:

You first have to put it in y = mx + b form

So, we first subtract 4x from both sides: -7y = -4x + 28

Divide both sides by -7

y = 4/7x - 4

Now to graph you have to start at the starting point which is -4

So we start with our point on -4 then move up 4 times and 7 times to the left. Mark the points then draw your line!

Answer 2

First solve the equation for y

Subtract 4x from both sides of the equation.
-7y=28-4x
Divide each term by -7and simplify.
y=-4+4x/7

Then graph the line using the slope and y-intercept

Slope: 4/7

Y-intercept: -4
