The graph shows two lines, A and B.

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.

    Hello.

    sloope intercept form is

    y=mx+b

    m=slope

    b=y intercept = where the line passes through the y axis.

    line M has slope of 1 and passes through y axis at - 5 (y intercept=5)

    equaton is therefor y=1x5 or y=x5

    Line N has slope of 1 and passes through y axis at 1 (y intercept=1)

    equaton is therefor y=1x1 or y=x1.

    compare

    line M: y=x2

    line N: y=x5

    There are different solutions so that means there is one solution.

    Have a nice day
