Question

A line has a slope of 2 and contains the polnts (1, 3) and (2,y). The value of y is

Answer 1

y = 5

Explanation:

The slope formula is y - y divided by x - x.

So, we put together numbers we already know:

`(y-3)/(2-1)=(2)/(1)`

(2 is also equal to 2/1)

So, now we have to think what minus 3 equals 2?

5

HOW TO CHECK IF THIS IS CORRECT:

`(5-3)/(2-1)=(2)/(1)` ✔
