2.Given points (x1, x2) and (y1, y2), what is the equation for slope?
3.What is the slope of a linear function containing the points (1, 1) and (3, 5)? Show your work.
4. Plot the two points from part b on the graph, and then draw a line through the points. Circle the point where the line crosses the y-axis.
5. Christa's friend Edrei takes the bus to school. She starts at a distance of 8 miles from the school. After 10 minutes on the bus, she is 4 miles from the school. After 20 minutes, she is 0 miles from the school. Use the steps to find the equation that describes Edrei's distance from school as she rides the bus.
1. Find the slope of the line using the points (10, 4) and (20, 0).
2. Identify the starting value, b.
3. Write the equation that represents this situation in the form y = mx + b.
6.The temperatures in Hillsbury over a span of 4 hours on April 7 are described by the function y = 4x + 5. The temperatures are recorded again on July 7. The temperatures on this day are described by the function y = 4x + 35. Complete the sentences to describe the new equation.
1.The slope in the new equation [has/has not] changed. This means the rate of temperature increase on July 7 was [different from/the same as] the rate on April 7.
2.The y-intercept of the new equation is [lower/higher]. This means the temperature when recording started on July 7 was _°F instead of _°F.
