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

Answer:

The missing y-coordinate is  4

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 = $\frac{y2- y1}{x2- x1}$,

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

Substituting the given values of the problem, we get

0 =$\frac{(y-4)}{(-2-3)}$

0 =$\frac{(y-4)}{(-5)}$

$0(-5) = y-4$

y – 4 = 0

y = 4

Hence, the y co – ordinate is 4.
