y=4x+8.
Simply plug in any number you wish into x and then calculate the corresponding y. For instance, if I said x was 2, then y would be 4*2+8=16 and my answer would be the ordered pair, (2,16).

How do you solve y equals 4x-8 and y equals 2x plus 10?
y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)
Y equals x2 - 4x plus 8?

What is the solution of y equals 4x-8 and y equals 2x plus 10?
x = 9 and y = 28
What are the intercepts for the line -4x plus y equals 8?
-4x + y = 8At the x-intercept, 'y' is zero.-4x = 8-x = 2x = -2At the y-intercept, 'x' is zero.y = 8
How would you solve for y in this problem 4x plus y equals 8?
You cannot solve one linear equation in two variables. You can express y in terms of x but that is NOT solving for y.
What is 4x plus 2y equals -8 written in slope-intercept form?
4x + 2y = -8 → 2y = -4x - 8 → y = -2x - 4
How do you solve y equals 4x-8 and y equals 2x plus 10?
y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)
What is the answer to 4x plus y equals 8 x plus 2y equals 5?
x = 11/7 and y = 12/7
Is 8 plus y equals 4x a linear equation?
Yes.
4x plus 2y equals -12 8x plus 6y equals -4?
x = -8, y = 10
Y equals -x2 plus 4x-3?
