1. 2.5 Writing Equations in Slope Intercept Form
y=mx+b

2. Writing an equation in “Slope Intercept Form” from a graph
Need to find m and b
To find m: count your slope or use the formula
To find b: locate it on the y-axis
Plug in m and b into y=mx+b

5. To write an equation given points (x1,y1) and (x2,y2)
Find “m” using the equation
Find “b” by plugging in: m and (x, y) to the equation y= mx + b.
Write the equation in slope-intercept form using the “m” found in step 1 and the “b” value calculated in step 2.
