Question

Which of the following is true of points on the line y=5/3 x + 1/2? (1) For every 3 units that increases, y will increase by 5 units. (2) For every 5 units that x increases, y will increase by 2 units. (3) For every 2 units that x increases, y will increase by 1 unit. (4) For every 1 unit that x increases, y will increase by 2 units.

Answer 1

4) For every 1 unit that x increases, y will increase by 2 units.​

1) For the function y=5/3x +1/2

If we remember that "rise over run" mnemonics, that'll make it easier to memorize it.

2) Plotting the graph of this function. Look at point A (1,2)

Counting from bottom to up (2 units "rise" on the y-axis, point A is 1 unit to right "run". So, For every 1 unit that x increases, y will increase by 2 units.​
