**Warm up Tell whether the relation is a function.**

{(-1, 5), (-3, 2), (2, 0), (1, 2)} Evaluate: f(x) = 2x2 – 4 when x = -3 Find the slope: (5, -1) and (7, -1) Tell whether the lines are parallel, perpendicular, or neither. Line 1: (-1, 6) and (2, 8) Line 2: (3, 2) and (1, 5)

**equation of a line given: The slope and the y intercept of the line?**

Essential Questions How can you find an equation of a line given: The slope and the y intercept of the line? The graph?

5
**I. How to Write an Equation of a Line Given m and b**

1. Write down y = mx + b 2. Substitute slope for m and y-intercept for b. 3. Simplify the equation

6
**Write the equation of the line given m and b.**

Ex. 1 Slope is -5 and y-intercept is 2 y = -5x + 2 Ex. 2 Slope is -1/2 and y-intercept is -2 y = -½x – 2

7
**Write the equation of the line given m and b.**

Ex. 3 Slope is 0 and y-intercept is 3 y = 3 Ex. 4 Slope is 1/3 and y-intercept is 0

8
**II. How to Write an Equation of a Line Given a Graph**

Write down y = mx + b Use any 2 “good” points on the graph to find the slope, m. Find the y-intercept on the graph, b. Substitute slope for m and y-int for b into the equation y = mx + b.
