20 points me ! graph the following lines and write the equation in slope-intercept form. through the points (4,2) and (3,1).

y= x-2

To draw this on the graph use the y-intercept to count the number of units you need to move up or down along the y axis. Then to plot the second point using the slope value to determine how many units to move up or down from the y-intercept point in this case it is 1. join the points to draw the line of slope intercept on the graph

Solution:

Find the slope in order to find the line of equation

m= y2-y1/x2-x1

Take both the coordinates and name it A (4,2) B(3,1) for convenience

m= 1-2/3-4

m=-1/-1

m=1 (slope)

Now find the y intercept using the equation below

y=mx+ b

where

y = y coordinate

m= slope

x= x coordinate

b= y intercept

SO

Note: use any of the coordinate the answer would be the same in either case

I will be using the coordinate (4,2)

y=mx+b

2=(1)(4)+b

2-4=b

-2=b

So the equation is

y= x-2

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft
