Question

# Please help I'm in summer school Look at the graph. Cost of Toy Cars A graph with cars on the x-axis and cost on the y-axis. A line goes through points (0, 0), (2, 3), (4, 6). What is the cost of 18 toy cars? $12 $20 $22 $27

Answer

$27

- Find the equation of the line using point-slope formula where y2 - y1 = m(x2 - x1) and m is the slope.
- Substitute the values of x and y to obtain the equation of the line.
- Substitute x in the equation of the line with 18 to get the cost of 18 toy cars.
