1. Warm Up 10/10/18 1) Write the equation in 2) Evaluate 𝟐 𝟓 −𝟓 ÷𝟗 𝟏𝟏
slope intercept form
if the line passes through
(-3, 4) with a slope of -5.

2. Writing Equations in Slope-Intercept Form (Part B)
Ch. 4-2
Writing Equations in
Slope-Intercept Form
(Part B)

3. ӿ Practice Write an equation of the line that passes
through (3, 1) & (2, 4).
Slope intercept form* y=mx+b
*we need slope(m) and y-intercept (b)
First Step find the slope:
𝒎= 𝒚𝟐−𝒚𝟏 𝒙𝟐−𝒙𝟏

4. ӿ Practice Write an equation of the line that passes
through (3, 1) & (2, 4).
Slope intercept form* y=mx+b
*we have m= -3, now need y-intercept (b)
Second Step use either point find the y-intercept:

5. ӿ Practice Write an equation of the line that passes
through (3, 1) & (2, 4).
m= -3 and b= 10
Step 3: Write the equation in slope-intercept form y=mx+b
