Exploring Linear Function Equations

What is the first step in finding the slope from a table of values?

• Identify the y-intercept

• Divide the y-values by the x-values

• Calculate the change in y-values

• Calculate the change in x-values

If the y-values in a table increase by 4 and the x-values increase by 5, what is the slope?

• 4/5

• 5/4

• 1/5

• 5/1

How do you find the y-intercept if it is not given in the table?

• Use the midpoint of the table

• Use the first point in the table

• Use any point and solve for b

• Use the last point in the table

What is the slope of the line given by the equation 2x + 3y = -9?

• -2/3

• 2/3

• -3/2

• 3/2

How do you transform an equation from point-slope form to slope-intercept form?

• Multiply both sides by the slope

• Subtract the slope from both sides

• Add the slope to both sides

• Distribute the slope and solve for y

What is the slope of the line given by the equation 5x - 6y = -18?

• 6/5

• -5/6

• -6/5

• 5/6

What is the equation of a line parallel to y = 7/4x - 3 that passes through the point (-5, 5)?

• y = -7/4x - 55/4

• y = -7/4x + 55/4

• y = 7/4x - 55/4

• y = 7/4x + 55/4

What is the equation of a line parallel to y = -6x + 2 that passes through the point (3, -1)?

• y = 6x - 8

• y = 6x + 8

• y = -6x - 8

• y = -6x + 8

What is the opposite reciprocal of the slope 7/3?

• 7/3

• -3/7

• 3/7

• -7/3

What is the equation of a line perpendicular to y = 1/2x + 3 that passes through the point (-3, 0)?

• y = -2x - 6/5

• y = -2x + 6/5

• y = 2x - 6/5

• y = 2x + 6/5
