Question

Using the slope and the y-intercept, graph the line represented by the following equation. Then select the correct graph. 2x - y + 4 = 0

Answer 1

Go up to 4 on the y axis, and then go up 2 and over 1, then graph.

Answer 2

slope =2 and y intercept =4

Explanation:

Using the slope and the y-intercept, graph the line represented by the following equation.

2x - y + 4 = 0

To get slope and y intercept we write the equation in the form of

`y=mx+b` where m is the slope and b is the y intercept

`2x - y + 4 = 0`, solve for y

Subtract 2x on both sides

`- y + 4 = -2x`

Subtract 4 on both sides

`- y = -2x-4`

Divide both sides by -1

`y =2x+4`

Slope =2 and y intercept = 4

now start graphing at y intercept (0,4)

for slope we move up by 2 units and right by 1 units
