If the point (-1/2, y) lies on the line whose equation is 2x - 3y = 6, what is the value of y?

Plug in the known x value

2(-1/2)-3y=6
-1-3y=6
-3y=7
y=-7/3

Final -7/3

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
