Question

How do you write an equation of a line given y-intercept -8 and slope 3/4

Answer 1

Hello there! :-)

If we are given the slope of the line and its y-intercept, we can fine the equation of the line in a flash.

First, the equation of the line should be written in slope-intercept form:

y=mx+b

In this equation, m is the slope, and b is the y-intercept.

We are given that  the slope is 3/4, and -8 is the y-intercept.

Therefore, the equation of the line is y=3/4x-8.

Good luck. :)

Answer 2

Answer:

$y = \frac{3}{4} x-8$

Step-by-step explanation:

You can us the equation y = m x + c to answer this question.

In ,

y = m x + c

m = slope

c = y - intercept

So, they have already given in the question that,

m = 3/4

c = (-8)

Therefore, you can simply put 3/4 and (-8) instead of m and c respectively like this.

y = m x + c

y = 3/4x - 8

Hope this helps you.
