All points that lie on that line
y−y1=m(x−x1)y - y_1 = m(x - x_1)y−y1=m(x−x1)
One point and the slope
m=y2−y1x2−x1m = \frac{y_2 - y_1}{x_2 - x_1}m=x2−x1y2−y1
2x−3y+12=02x - 3y + 12 = 02x−3y+12=0
They have the same slope
Slopes are negative reciprocals
−1m-\frac{1}{m}−m1
ax+by+c=0ax + by + c = 0ax+by+c=0
The y-intercept
General form
−25-\frac{2}{5}−52
