Solve a system of equations graphically (slope intercept form word problem)IXL (8th grade AA.3) Question 10 Two groups of workers are painting a bridge in the bay. The first group is responsible for painting the north side of the bridge, and the second group is responsible for painting the south side of the bridge. The first group has already painted 5 kilometers of the bridge and is painting 1 additional kilometer per day. The second group has already painted 3 kilometers of the bridge and is painting 2 additional kllometers per day. After how many days will the two groups have painted the same amount of the bridge? Write a system of equations​

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.
