The equation of a line in slope-intercept form is.
y=mx+b
where m represents the slope and b, the y-intercept.
Rearrange 3x−2y+4=0 into this form
add 2y to both sides.
3x−2y+2y+4=0+2y
⇒2y=3x+4
divide ALL terms on both sides by 2
2y2=32x+42
⇒y=32x+2← in form y=mx+b
⇒slope =m=32
The equation of a line in point-slope form is.
y−y1=m(x−x1)
m is slope and (x1,y1) a point on the line
For parallel line m=32 and (x1,y1)=(1,6)
⇒y−6=32(x−1)← in point-slope form
Distributing the bracket and simplifying gives the equation in an alternative form.
y−6=32x−32
⇒y=32x−32+6
⇒y=32x+92← in slope-intercept form
graph{(y-3/2x-2)(y-3/2x-9/2)=0 [-10, 10, -5, 5]}
