Simultaneous Equations
Understand that two linear equations can be solved simultaneously by finding the point where their graphs intersect, and interpret this graphically and algebraically as the pair of values satisfying both equations

Question 1 of 3
On a coordinate grid the line showing Alex’s bike distance passes through (0, 3) and (4, 11). The line showing Sam’s bike distance passes through (0, 15) and (5, 5). Looking at the graph, which point is the approximate intersection of the two lines?
Question 2 of 3
Which ordered pair (x, y) satisfies both equations: x + y = 5 and x - y = 1?
Question 3 of 3
Two lines are drawn on a coordinate grid with the equations y=4x−2 and y=−2x+10. Which point lies on both lines?
