Multiply equation A by –7. Multiply equation B by 7. Question 17 (Multiple Choice Worth 1 points) (08.03 MC) Two equations are given below: a – 4b = 10 a = b – 2 What is the solution to the set of equations in the form (a, b)? (–5, –3) (–6, –4) (–4, –2) (–8, –6) Question 18 (Multiple Choice Worth 1 points) (08.02 LC) Which description best describes the solution to the following system of equations? y = –2x + 8 y = –x + 5 Line y = –2x + 8 intersects the origin. Lines y = –2x + 8 and y = –x + 5 intersect the x-axis. Lines y = –2x + 8 and y = –x + 5 intersect the y-axis. Line y = –2x + 8 intersects the line y = –x + 5. Question 19 (Multiple Choice Worth 1 points) (08.03 LC) A set of equations is given below: Equation C: y = 3x + 7 Equation D: y = 3x + 2 Which of the following best describes the number of solutions to the given set of equations?

    4th one no solution because the lines are parallel and never intersect

    Rachel is 11 years older than Scott. Rachel's age is 7 years less than two times Scott's age. The system below models the relationship between Rachel's age (r) and Scott's age (s): r = s + 11 r = 2s – 7 Which is the correct method to find Rachel's and Scott's ages? Solve r + 11 = 2r – 7 to find the value of s. Solve s + 11 = 2s – 7 to find the value of s. Write the points where the graphs of the equations intersect the x-axis. Write the points where the graphs of the equations intersect the y-axis.
