Graphing Slope-Intercept Form Equations

What is the y-intercept of a line in the equation y = mx + b?

• The point where the line crosses the y-axis

• The point where the line crosses the x-axis

• The slope of the line

• The x-coordinate of the line

How do you determine the slope of a line using two points?

• By subtracting the y-coordinates and dividing by the difference in x-coordinates

• By multiplying the x and y coordinates

• By adding the x-coordinates of the points

• By finding the midpoint of the two points

What does the 'rise' in 'rise over run' refer to?

• The vertical distance between two points

• The horizontal distance between two points

• The angle of the line

• The total distance between two points

When graphing the equation y = 1/2x - 2, where do you start?

• At the x-intercept

• At any random point on the graph

• At the y-intercept, which is -2

• At the origin

How do you use the slope to find the next point after the y-intercept?

• Go up by the slope value and left by 1

• Go up by the run and right by the rise

• Go up by the rise and right by the run

• Go down by the slope value and right by 1

In the equation y = -2x + 1, what does the negative sign in the slope indicate?

• The line is vertical

• The line slopes downward

• The line slopes upward

• The line is horizontal

How do you graph a line with a slope of -2?

• Go up 2 and right 1

• Go down 1 and right 2

• Go down 2 and right 1

• Go up 1 and right 2

What is the implicit slope of the equation y = 2x - 4?

• 2

• 1

• 4

• 0

When graphing y = 2x - 4, what is the first step?

• Draw a vertical line

• Plot the x-intercept

• Plot the y-intercept at -4

• Draw a horizontal line

How do you complete the graph of y = 2x - 4 after plotting the y-intercept?

• Go up 2 and left 1

• Go up 1 and right 1

• Go down 2 and right 1

• Go up 1 and left 1
