Answer:

first find the slope using the two given points, use the formula rise/run.

point1=(x1,y1) point2=(x2,y2)

ex. point1= (2,1) point 2= (4,4) use the formula

(1-4)/(2-4)= -3/-2=3/2 our slope is m= 3/2

2nd step use the slope and one point to find the y- intercept, use the formula y= mx+ b

ex. use point 1= (2,1) slope (m)=1/2

1=3/2(2)+b , 1=3+b, b= -2

.

3rd step plug or substitute the value of slope (m) and b to the slope intercept form y=mx+b

ex. m=3/2 b= -2

y= 3x/2 -2 is your equation of the line
