7. Example 6 Similar Problem: Write the equation of the line in point-slope form that has a slope of -4/5 and passes through the point (3, 11). y2 - y1 = m(x2 - x1) y - 11 = -4/5 (x - 3)
8. Example 7 Similar Problem: Write the equation of the line in slope-intercept form that has a slope of -4 and passes through the point (2, 0). y = mx + b 0 = -4(2) + b 0 = -8 + b 8 = b y = -4x + 8
9. Example 8 What is the equation for Standard Form? Ax + By = C
10. Example 9 Similar Problem: Change the linear equation y - 8 = 4(x - 3) to Standard Form. y- 8 = 4(x - 3) Solve for y. Distribute 4. y- 8 = 4x – 12 Add 8 to each side. y= 4x - 4
