What is (4,7), 3
100
Evaluate the equation for x = -1 y = 2x + 5
What is 3, 5, 7?
100
What is the formula to find slope?
What is y 2 - y 1 over x 2 - x 1
200
Find the slope of the line that passes through (6,2) and (-2,-6)
What is 1?
200
Write the equation in slope-intercept form and find the slope and y-intercept. 5y - 3x
What is y = 3/5x + 0; m = 3/5; b = 0
200
Identify the point and slope y - 1 = 1/3(x +6)
What is (-6,1), 1/3
200
Constant or Variable? x = -1, 0, 3, 5, 9 y = 1, 3, 6, 10, 4
What is Variable?
200
How would you graph y = -7?
What is the x would be zero, so you would go down 7 on the y axis and plot the point. All of the x's would be 0, so it would be a horizontal line.
300
What kind of lope would you have with a line that passes through points (4,-4) and (9,-4)? positive, negative, zero or undefined?
What is zero?
300
Find the x and y intercept of 4x - 3y = 12.
What is (3,0) and (0,-4)
300
Write the point-slope form of the equation: the line with slope 4 passing through (5, -2)
What is y + 2 = 4(x - 5)
300
constant or variable? x = 0, 1, 3, 7, 8 y = 1, 3, 7, 15, 17
What is constant?
300
Explain how you would graph x = 5?
What is all of the x's would be 5, and the y's would be zero, so it would be a vertical line.
400
A wheelchair ramp rises 1.5 feet for every 18 feet of horizontal distance it covers. Find the rate of change of the ramp.
What is 1/12?
400

What is not linear?
500
Which variable is the dependent variable and which variable is the independent variable?
What is x is independent and y is dependent?

Write an equation that has the same y-intercept as y = 2x + 4.
What is y = x + 4?
500
Write the point slope of the equation the line with slope 5 passing through (0,6)
