Graphing Lines in Slope Intercept Form

What represents the slope in the equation y = mx + b?

• x

• b

• m

• y

What does the y-intercept represent in a graph?

• The point where the line crosses the y-axis

• The point where the line crosses the x-axis

• The coefficient of x

• The slope of the line

In the equation y = mx + b, what does 'b' stand for?

• The x-intercept

• The slope

• The coefficient of y

• The y-intercept

If an equation is in the form y = 3x + 4, what is the slope?

• y

• x

• 3

• 4

In the equation y = -1/2x + 2, what is the y-intercept?

• y

• x

• -1/2

• 2

What is the slope in the equation y = -2x + 3?

• -3

• -2

• 3

• x

How do you graph a line starting from the y-intercept?

• Start at the y-intercept and use the slope to find the next point

• Draw a line through the origin

• Start at the x-intercept and move up

• Move according to the slope from the origin

What does a negative slope indicate about the direction of a line?

• The line moves from bottom left to top right

• The line moves from top left to bottom right

• The line is horizontal

• The line is vertical

If the slope is -2, how do you move to plot the next point from an initial point?

• Up 2, right 1

• Down 2, right 1

• Down 1, right 2

• Down 2, left 1

How do you find the next point on a graph if the slope is a fraction like -1/2?

• Down 1, right 2

• Up 1, right 2

• Down 2, right 1

• Up 2, right 1
