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:
slope =2 and y intercept =4
Step-by-step 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
