Help!!!!!!!!!!!!!!!!!!!

Answer 1

Answer:

• 1) y = (-2/3)x +2/3
• 2) y = (6/5)x -23/5
• 5) y = (-1/6)x +4/3
• 6) y = x -2

Step-by-step explanation:

A simple, mechanical way to do these (perpendicular lines) is ...

• replace any constant with 0
• swap the x- and y-coefficients, negating one
• for point (h, k), replace x with (x-h) and y with (y-k)
• solve for y (to get slope-intercept form)

1) 3x -2y = 0 . . . . . step 1

... 2x +3y = 0 . . . . step 2

... 2(x -1) +3(y -0) = 0 . . . . step 3

... 2x -2 = -3y . . . . eliminate parentheses, subtract 3y

... y = (-2/3)x +2/3 . . . . divide by the coefficient of y

2) 6(x -3) -5(y +1) = 0 . . . . after step 3

... 6x -23 = 5y . . . . . . . . . . simplify, add 5y

... y = (6/5)x - 23/5 . . . . . divide by the coefficient of y

5) (x+4) +6(y-2) = 0 . . . . . after step 3

... x -8 = -6y . . . . . . . . . . . simplify, subtract 6y

... y = (-1/6)x +4/3 . . . . . . divide by the coefficient of y

6) (y +5) = (x +3) . . . . . . . after step 3

... y = x -2 . . . . . . . . . . . . subtract 5
