99 POINTSQUESTION 1Use the slope formula to find the slope of the line passing through the given points.(2, 1) and (4, –5)QUESTION 2Explain why the triangles below are proportional to each other.Graph of a line containing the points: A(–10, –5), C(–2, –1), D(4, 2), and F(8, 4). Point B is plotted at (–2, –5) to form triangle ABC and point E is plotted at (8, 2) to form triangle DEF.QUESTION 3What is the slope of this line? How much does each pencil cost?QUESTION 4A bus travels at a constant speed of 55 miles per hour. How far will it travel in 5 hours?QUESTION 5Bob is selling floral arrangements. Each arrangement uses 1 vase and 15 tulips. Each vase costs Bob $4.00. Let C be the total cost of the arrangement and t be the cost of 1 tulip. Write an equation, in slope-intercept form, that represents the total cost of each arrangement to Bob.QUESTION 6Does this graph show a proportional relationship? Why or why not?QUESTION 7Write the equation of the line containing the point (4, 6) and having a slope of 4 in slope-intercept form.QUESTION 8This graph shows Matt's progress as he walks in the direction of Grandma's house: Coordinate plane with x-axis labeled Time in hours and y-axis labeled Distance in miles.
