Question

7. The points (3,5) and (2, y) are on a line with a slope of 3. Find y.​

Answer 1

We get value of y: y = 2

Explanation:

The points (3,5) and (2, y) are on a line with a slope of 3. Find y.​

We can find y using formula of finding slope of a line.

The formula is:
`Slope=(y_2-y_1)/(x_2-x_1)`

We have
`x_1=3, y_1=5, x_2=2, y_2=y` and Slope = 3

Putting values and finding y

`Slope=(y_2-y_1)/(x_2-x_1)\\3=(y-5)/(2-3)\\3=(y-5)/(-1)\\-1(3)=y-5\\-3=y-5\\y=-3+5\\y=2`

So, we get value of y: y = 2
