15. Convert to standard form. multiply both sides by 7
16. Write the equation of the line parallel the line 4x – 5y = 7 that passes through the point (-3, 7) What is the slope of the given line? y – y 1 = m (x – x 1 )
17. Write the equation of the line perpendicular the line 3x + 2y = 9 that passes through the point (2, 5) What is the slope of the given line? y – y 1 = m (x – x 1 )
