Find the equation of a line that is parallel to y = x + 1 and passes through the point (3,-4). Give your answer in the form y = mx + b.

Given:

The equation of a line is:

A line is parallel to the given line and passes through the point (3,-4).

To find:

The equation of the line in the slope intercept form.

Solution:

The slope intercept form of a line is:

            ...(i)

Where, m is the slope and b is the y-intercept of the line.

We have,

               ...(ii)

On comparing (i) and (ii), we get

Slope of the given line is 1.

We know that the slopes of parallel lines are equal. So, the slope of the required line is 1.

The required line passes through the point (3,-4) with slope 1. So, the equation of the required line is:

Subtracting 4 from both sides, we get

Therefore, the equation of the required line is .

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
