What is the equation of the line whose y-intercept is 3 and slope is 1?

Solution:

Given, the y-intercept is 3

The slope is 1

We have to find the equation of the line.

The equation of the line in slope intercept form is given by

y = mx + b

Where, m is the slope

b is the y-intercept.

Here, m = 1 and b = 3

So, y = x + 3

Therefore, the equation of the line is y = x + 3.

Example:  What is the equation of the line whose y-intercept is 8 and slope is 3?

Solution:

Given, the y-intercept is 8

The slope is 3

We have to find the equation of the line.

The equation of the line in slope intercept form is given by

y = mx + b

Where, m is the slope

b is the y-intercept.

Here, m = 3 and b = 8

So, y = 3x + 8

Therefore, the equation of the line is y = 3x + 8.
