Question

A line with a slope of 0 contains the point (3, 4). The point ( -2,?) is also on the line. What is the missing y-coordinate?

Answer 1

The missing y-coordinate is 4

Step-by-step explanation:

Given:

A line with a slope of 0 contains the point (3, 4).

The point ( -2,?) is also on the line.

To find:

the missing y-coordinate=?

Solution:

Now, we know that, slope of line =
`(y2- y1)/(x2- x1)`,

where (x1, y1) and (x2, y2) are points on the line

Substituting the given values of the problem, we get

0 =
`((y-4))/((-2-3))`

0 =
`((y-4))/((-5))`

`0(-5) = y-4`

y – 4 = 0

y = 4

Hence, the y co – ordinate is 4.
