2. Example 9 m = 3 y – y1 = m (x – x1) pt: (5, -2) y – (-2) = 3 (x – 5)
Write the equation of the line parallel to the line y = 3x + 4 containing the point (5, -2).
m = 3
y – y1 = m (x – x1)
pt: (5, -2)
y – (-2) = 3 (x – 5)
y + 2 = 3x - 15
y = 3x - 17

3. Example 5
Graph f(x) = 3x – 2 and find the slope and y-intercept
Slope= _______
y-intercept = ______ x y 1 -2 1

4. Example 6

Slope= _______
y-intercept = ______ x y 3 2 1

5. Example 7
Graph by hand and identify the slope and y-intercept.
Slope= _______
y-intercept = ______ x y 1 -3 -3
