5.1 Write Linear Equations in Slope-Intercept Form

Y= this stands for the y coordinate. Ex:(0,5)

X= This stands for the x coordinate. Ex: (4,0)

M= this stands for the slope of the line. Ex: in y=2x+4 the slope is 2

b= this stands for the y-intercept of the line Ex: in 2x+4 the y-intercept would be 4

This is slope-intercept form!

What I call the double point- slope equation:

y₂-y₁ / x₂-x₁

_{This helps find the slope when the problem gives us two points.}
