A coordinate plane is shown with two lines, A and B, graphed. Line A has a slope of negative 1 and crosses the y axis at 5. Line B has a slope of positive 1 and crosses the y axis at 3.
How many solutions are there for the pair of equations for lines A and B? Explain your answer.
2) Consider the following set of equations:
Equation A: y = 2x + 4
Equation B: y = 3x + 1
Which of the following is a step that can be used to find the solution to the set of equations?
For question 1) Line A's Gradient= -1 y=-x+5 where 5 is the y-intercept Line B's Gradient= 1 y=x+3 where 3 is the y-intercept By equating two equations.... -x+5=x+3 2x+3=5 2x=2 x=1 1 solution For question 2) answer would be the first option
