1. Using the slope-intercept form of a line, find the equation of the line with slope 3/2 and y-intercept –2. Then graph the line on the grid provided and explain how you determined your graph.

Verified Answer :

You would use rise over run. So you would 3x-2 then 2x-2 which would give you -6 as your x. and -4 for y. then you graph your answer.

Answer:

The equation of the line is equal to

\(y=\frac{3}{2}x-2\)

Step-by-step explanation:

we know that

The equation of the line in slope-intercept form is equal to

\(y=mx+b\)

where

m is the slope of the line

b is the y-intercept of the line ( value of y when the value of x is equal to zero)

In this problem we have

\(m=\frac{3}{2}\)

\(b=-2\)

so

the equation of the line is equal to

\(y=\frac{3}{2}x-2\)

To plot the graph find the intercepts of the line

The y-intercept is the point \((0,-2)\)

Find the x-intercept

The x-intercept is the value of x when the value of y is equal to zero

For \(y=0\)

\(0=\frac{3}{2}x-2\)

\(\frac{3}{2}x=2\)

\(x=\frac{4}{3}\)

the x-intercept is the point \((4/3,0)\)

plot the two points and draw the line through the two points
