Find the x-intercept and the y-intercept for 2x+y=8 then use them to g

1.	Find the x-intercept and the y-intercept for 2x+y=8 then use them to graph the line.
Answer» Find the x-intercept by SUBSTITUTING in 0 for y and solving for x. Find the y-intercept by substituting in 0 for x and solving for y. Let's find the x-intercept FIRST: 2x + (0) = 8 2x = 8 Divide both sides by 2 to isolate and solve for the variable "x", or the x-intercept. x = 4 (x-intercept) Now find the y-intercept: 2(0) + y = 8 Multiply 2 and 0. y = 8 (y-intercept) You have found the x-intercept to be 4 and the y-intercept to be 8. To graph the LINE, place a point on (4, 0) ← x-intercept and a point on (0, 8) ← y-intercept. Your line should look like the attached image :)

Find the x-intercept by SUBSTITUTING in 0 for y and solving for x.

Find the y-intercept by substituting in 0 for x and solving for y.

Let's find the x-intercept FIRST: 2x + (0) = 8

2x = 8

Divide both sides by 2 to isolate and solve for the variable "x", or the x-intercept.

x = 4 (x-intercept)

Now find the y-intercept: 2(0) + y = 8

Multiply 2 and 0.

y = 8 (y-intercept)

You have found the x-intercept to be 4 and the y-intercept to be 8. To graph the LINE, place a point on (4, 0) ← x-intercept and a point on (0, 8) ← y-intercept.

Your line should look like the attached image :)
