Question

Write the equation of a line that is parallel to y=-7 and that passes through the point 7,5)

Answer 1

y = 5

Explanation:

Let y = mx + b (1) is the equation of a line we need to find

As we know, it is parallel to y= -7 (with the slope is 0)

However, the slopes of parallel lines are equal

=> the slope of (1) is 0

<=> y = b

And that passes through the point (7,5), we have:

5 = b

=> the equation of a line as the answer of this problem is:

y = 5

Hope it will find you well.
