Finding Slope Equations

How do you calculate slope using a graph?

• rise over run

• run over rise

• look at the y intercept

• look at the x intercept

What does 'b" represent in y=mx+b

• y-intercept

• macaroni

• nothing

• slope

What is the slope in the picture?

• Positive

• Negative

• Zero

• Undefined

What direction will the line on a graph be going if the slope is positive?

• up

• down

Identify the slope and y-intercept of the equation y = 4x - 7.

• Slope = 7, Y-intercept = -4

• Slope = 4, Y-intercept = -7

• Slope = 4, Y-intercept = 7

• Slope = -7, Y-intercept = 4

Oliver and Anika are standing at two different points in a park. Oliver is standing at point (-1, 4) and Anika is standing at point (3, 10). If a line is drawn between these two points, calculate the slope of that line.

Write the equation of the line with a slope of -2 and a y-intercept of 6 in slope-intercept form.

• y = 2x + 6

• y = 6x - 2

• y = -2x - 6

• y = -2x + 6

Identify the slope and y-intercept of the equation y = -5x + 3.

• Slope = 5, Y-intercept = -3

• Slope = 0, Y-intercept = 5

• Slope = 3, Y-intercept = -5

• Slope = -5, Y-intercept = 3

Use the slope-intercept form to solve the problem: A line has a slope of -4 and passes through the point (0, 9). Find the equation of the line.

• y = -4x - 9

• y = -4x

• y = -4x + 9

• y = 4x + 9

Calculate the slope of the line passing through the points (2, 3) and (5, 9).
