Writing equations in slope intercept form from a Table

If a table shows a constant rate of change, what type of function does it represent?

• Quadratic function

• Exponential function

• Linear function

• Cubic function

What is a non-proportional linear function?

• A non-proportional linear function passes through the origin.

• A non-proportional linear function has a y-intercept that is zero.

• A non-proportional linear function does not pass through the origin and has a y-intercept that is not zero.

• A non-proportional linear function is a horizontal line.

If the slope of a line is -1/2, what does this indicate about the line?

• It indicates that for every 2 units the line moves to the right, it moves down 1 unit.

• It indicates that the line is vertical and does not move horizontally.

• It indicates that the line moves up 1 unit for every 2 units it moves to the right.

• It indicates that the line has a positive slope and rises to the right.

How can you find the slope from a table of values?

• Calculate the average of all y values.

• Determine the maximum y value minus the minimum y value.

• Calculate the change in y divided by the change in x (rise/run) between two points.

• Add all x values together and divide by the number of points.

How do you convert a table of values into slope-intercept form?

• Identify the slope and y-intercept from the table, then write the equation as y = mx + b.

• Calculate the average of the values in the table and use it as the slope.

• Plot the points on a graph and connect them with a straight line.

• Use the values to create a quadratic equation instead.

How do you determine if a linear function is proportional?

• A linear function is proportional if it passes through the origin (0,0) and can be expressed in the form y = mx.

• A linear function is proportional if it has a constant slope that is not equal to zero.

• A linear function is proportional if it intersects the y-axis at a point other than zero.

• A linear function is proportional if it can be represented by a quadratic equation.

What is slope-intercept form?

• y = mx + b, where m is the slope and b is the y-intercept
