Algebra I Notes Section 5.2: Use Linear Equations in Slope-Intercept Form In this lesson we will again write equations of a line, but you will have to find the slope and y-intercept mathematically. You still need to know the _______ of the line and the ____________ of the line to write an equation using slope-intercept form. slope y-intercept Example 1: Write an equation of a line that passes through the point (-3, 0) and has a slope (m) of . y = mx + b
Example 2 Write an equation of a line from a graph. Point: (3, 4)
Example 3: Write an equation of a line that passes through (3, 0) and (2, -4). (Slope Formula: )
Example 4: Write an equation for a linear function f that has the given values. f(2) = 8 and f(-2) = -4
