1.) Substitute the x-values in the chart for the x in the equation.
y = 0.5x + 18
y = 0.5(6) + 18
y = 3 + 18
y = 21
Repeat this step for the other values in the chart. After doing that, your answers should be y = 22 (corresponds to 8) and y = 23 (corresponds to 10.) Let me know if you need to see those worked out.
2.) Substitute the x-values in the chart for the x in the equation.
y = 10(x + 6)
y = 10(6 + 6)
y = 10(12)
y = 120
Repeat this step for the other values in the chart. After doing that, your answers should be y = 140 (corresponds to 8) and y = 160 (corresponds to 10.) Let me know if you need to see those worked out.
FINAL ANSWERS:
1.) 21, 22, and 23
2.) 120, 140, and 160
Hope this is accurate & helpful!
