Graphing from Slope-Intercept Form and Slope Formula

What is the slope-intercept form of a linear equation?

• y = mx + b

• y = ax^2 + bx + c

• y = mx^2 + b

• y = x^2 + b

In the equation y = 2x + 1, what is the slope?

• 3

• 1

• 2

• 0

In the equation y = -3/5x + 2, what is the y-intercept?

• 3

• -2

• 2

• -3/5

What is the first step in graphing a linear equation?

• Finding the x-intercept

• Drawing the line

• Plotting the x-intercept

• Identifying the slope and y-intercept

How do you determine the direction of a positive slope?

• The line increases from left to right

• The line is vertical

• The line is horizontal

• The line decreases from left to right

What type of slope does a vertical line have?

• Undefined

• Zero

• Negative

• Positive

What is the slope of the line passing through the points (5, -4) and (-2, 6)?

• 10/7

• -10/7

• 7/10

• -7/10

If the slope of a line is zero, what does the line look like?

• Undefined

• Diagonal

• Horizontal

• Vertical

In the slope formula, what does the numerator represent?

• Change in y

• Sum of x values

• Sum of y values

• Change in x

What happens when you divide by zero in the slope formula?

• You get a positive slope

• You get a negative slope

• The slope is undefined

• You get zero
