Write the equation for a line with a y-intercept of 3 that also passes through the point (2,5).

y= x +3

Look at the 2 equations above. Choose the statement that best fits the comparison of the two equations.

a) The items have different y-intercepts and different rates of change.

b) The rates of change are the same, but the y-intercepts are different.

c) The items have the same y-intercepts and the same rate of change.

d) The y-intercepts are the same, but the rates of change are different.

What is the name of the method used to look at a graph and decide whether it is a function?

Vertical line test

Write the equation for the table.

y = -3x – 9

Draw a parabola to show when it would NOT represent a function?

Laying on its side

Look at the equations above. Choose the statement that best fits the comparison of the two equations.

b) The rates of change are the same, but the y-intercepts are different.

c) The items have the same y-intercepts and the same rate of change.

d) The y-intercepts are the same, but the rates of change are different.
