Question

Determine if the given points lies on the given line.

Answer 1

1. Fill in the x-coordinate in the function
$y = 2 \times 3 - 4$
$y = 6 - 4$
$y = 2$
We find that the y-coordinate is 2. So this point is on the graph.

2. Same work
$y = \frac{1}{4} \times 4 + 15$
$y = 1 + 15$
$y = 16$
We find that the y-coordinate is 16. So this point isn't on the graph.
