  • Question 1 (request help)

    Jaime purchased a $20 bus pass. Each time he rides the bus, a certain amount is deducted from the pass. The table shows the amount, y, left on his pass after x rides. Graph the data, and find the slope and y-intercept from the graph or from the table. Then write the equation for the graph in slope-intercept form.

  • Type below:

The table shows the temperature (y) at different altitudes (x). This is a linear relationship.

  • Question 3 (request help)

    Find the y-intercept for this relationship.

  • y-intercept=
