16. a) Is it true that two lines Line 1 and Line 2 are parallel if their slopes are equal m, = ma? b) Is it true that two lines Line 1 and Line 2 are perpendicular if the product of their slopes is equal to one? mi*mz = +1 c) Is it true to find the slope of a line from the given linear equation in two variables x and y, we should solve for y first and then find the slope m (coefficient of x)? 17. The equations of three lines are given below: Section 2.5 Examples 3, 4 Line 1: y = = x - 3 Line 2: 7y = 2x + 4 Line 3: 2y +7x = 6 a) find the slope of each line: m1, mz, my (solve each equation for y) b) Based on the corresponding slopes and the property determine whether (Line 1 and Line 2) are parallel, perpendicular, or neither. Explain your answer: write the corresponding property c) Based on the corresponding slopes and the property determine whether (Line 1 and Line 3) are parallel, perpendicular, or neither. Explain your answer: write the corresponding property d) Based on the corresponding slopes and the property determine whether (Line 2 and Line 3) are parallel, perpendicular, or neither. Explain your answer: write the corresponding property
