Based on the graph below, what are the x and y-intercepts?
X-intercept: (-2,0) or -2
Y-intercept: (0,6) or 6
100
Write the following equation in standard form:
y=-1/2x+3
x+2y=6
100
Tell if the two lines are parallel perpendicular or neither:
y=1/2x+2
y=-2x+4
Perpendicular! Negative reciprocal slopes!

What does the slope and y-intercept mean in your context?
Slope: The price of the car goes down by $502.43 every year.
Y-intercept: A car from this dealership would cost $7836.26, when it is 0 years old.
