Part b· 1 step

For the equation y=5x+6y = 5x + 6

  1. Substitute each xx value into the equation to find the corresponding yy value.

    For x=−2x = -2: y=5(−2)+6=−10+6=−4y = 5(-2) + 6 = -10 + 6 = -4
    For x=−1x = -1: y=5(−1)+6=−5+6=1y = 5(-1) + 6 = -5 + 6 = 1
    For x=0x = 0: y=5(0)+6=0+6=6y = 5(0) + 6 = 0 + 6 = 6
    For x=1x = 1: y=5(1)+6=5+6=11y = 5(1) + 6 = 5 + 6 = 11
    For x=2x = 2: y=5(2)+6=10+6=16y = 5(2) + 6 = 10 + 6 = 16

    The completed table is:

    x−2−1012y-4161116\begin{array}{|c|c|c|c|c|c|} \hline x & -2 & -1 & 0 & 1 & 2 \\ \hline y & \textbf{-4} & \textbf{1} & \textbf{6} & \textbf{11} & \textbf{16} \\ \hline \end{array}

Part d· 1 step

For the equation y=−4x+5y = -4x + 5

  1. Substitute each xx value into the equation to find the corresponding yy value.

    For x=−4x = -4: y=−4(−4)+5=16+5=21y = -4(-4) + 5 = 16 + 5 = 21
    For x=−1x = -1: y=−4(−1)+5=4+5=9y = -4(-1) + 5 = 4 + 5 = 9
    For x=0x = 0: y=−4(0)+5=0+5=5y = -4(0) + 5 = 0 + 5 = 5
    For x=1x = 1: y=−4(1)+5=−4+5=1y = -4(1) + 5 = -4 + 5 = 1
    For x=3x = 3: y=−4(3)+5=−12+5=−7y = -4(3) + 5 = -12 + 5 = -7

    The completed table is:

    x−4−1013y21951-7\begin{array}{|c|c|c|c|c|c|} \hline x & -4 & -1 & 0 & 1 & 3 \\ \hline y & \textbf{21} & \textbf{9} & \textbf{5} & \textbf{1} & \textbf{-7} \\ \hline \end{array}

Part f· 1 step

For the equation y=−3x−2y = -3x - 2

  1. Substitute each xx value into the equation to find the corresponding yy value.

    For x=−2x = -2: y=−3(−2)−2=6−2=4y = -3(-2) - 2 = 6 - 2 = 4
    For x=−1x = -1: y=−3(−1)−2=3−2=1y = -3(-1) - 2 = 3 - 2 = 1
    For x=0x = 0: y=−3(0)−2=0−2=−2y = -3(0) - 2 = 0 - 2 = -2
    For x=1x = 1: y=−3(1)−2=−3−2=−5y = -3(1) - 2 = -3 - 2 = -5
    For x=2x = 2: y=−3(2)−2=−6−2=−8y = -3(2) - 2 = -6 - 2 = -8

    The completed table is:

    x−2−1012y41-2-5-8\begin{array}{|c|c|c|c|c|c|} \hline x & -2 & -1 & 0 & 1 & 2 \\ \hline y & \textbf{4} & \textbf{1} & \textbf{-2} & \textbf{-5} & \textbf{-8} \\ \hline \end{array}
