day 1

2. Find the y-intercept: Linear equation:
An equation that models a linear function.
1. The y-coordinate of a point where the graph crosses the y-axis where x= 0
y-intercept:
Find the y-intercept:
y-intercept:
(0,2) or 2
y-intercept:
(0, -3) or -3
y-intercept:
(0,0) or 0

3. y = mx + b y = 5 y = -2x + 3 y = 6x y = 0x + 5

y = mx + b
slope
y-intercept
Identify the slope and y-intercept.
y = 5
y = -2x + 3
y = 6x
y = mx + b
y = mx + b
y =6x+ 0
y = 0x + 5 6
m =
y-int =
m =
y-int = -2
m =
y-int = 5 3

4. y = 2x - 3 y = mx + b y = mx + b 𝑦= 2 3 x + 7 m = 2 m = 2 3 y-int = -3
Write an equation in slope-intercept form given the slope (m) and y-intercept (b).
m = 2
y-int = -3
m = 2 3
y-int = 7
y = mx + b
y = mx + b
y = 2x - 3
𝑦= x + 7
