Please help! 25 points!<br> Write the equation of a line with slope 3/2 and Y-Intercept -2.

Hello there!

For this question, we can use slope-intercept form of a line. The following equation is the format for slope-intercept form:
$y=mx+b$

In this equation, m is the slope and b is the y-intercept. The slope and y-intercept is given. Thus, we just "plug in" the given values into the equation to get our answer. Replace "m" with "3/2" and replace "b" with "-2". After doing so, you get the following equation for the line.

$y= \frac{3}{2} x-2$

That should be your answer. Hope this helps! :)

Answer:

1/2 = 3/6

1/3 = 4/12

1/4 = 5/20

Step-by-step explanation:

To make equivalent fractions, you need multiply by 1. A number divided by itself is 1.

1/1 * x/x = x/x = 1
