1. Writing Linear Equations When Given a Point and the Slope Day 2

2. Warm Up
b = -1
b = -3
b = 121
b = -82

3. Writing Linear Equations When Given a Point and the Slope Day 2

4. Write an equation in slope intercept form when given the slope and a point.
y = mx + b -1 = 𝟏 𝟑 (6) + b
-1 = 2 + b b = -3

5. Write an equation in slope intercept form when given the slope and a point.
y = mx + b -5 = 0(2) + b
-5 = 0 + b b = -5
Equation y = 0x y = -5

6. y = mx + b -4 = undefined(1) + b
Write an equation in slope intercept form when given the slope and a point.
m = undefined (1, -4)
y = mx + b -4 = undefined(1) + b
You cannot solve because undefined is not a number.
Undefined slope lines are x = lines.
Look at the x value in the ordered pair and set x equal to that.
The equation is x = 1.

7. Practice
Write an equation in slope intercept form when given the slope and a point.
m = 5, (1,9)
m = 0, (-3,-6)
m = undefined, (-4,7)
y = 5x + 4
y = -6
x = -4
