Given the slope and a point on the line, use the point-slope formula for the equation of a straight line.

y-6 = (-5/9)(x-9)

This can be put into other forms.  For example, 

             Multiplying all terms by 9 results in   9y - 54 = -5(x-9) = -5x + 45

             Solving for y:  9y - 54 = -5x + 45
                                          +54 =        +54
                                      ---------------------------
                                         9y = -5x + 99

Then y = (-5/9)x + 11.

Find the equation of the lines perpendicular and parallel to 2x-3y=8 line through the point (-2,-4)
marysya [2.9K]

Answer:

y= -1.5x-7 is the equation of the perpendicular line

Here's why:

when we convert 2x-3y=8 to standard form, we get y= 2/3x-8/3. This means the perpendicular line will have a slope of the negative reciprocal of the original one, so the perpendicular slope is -1.5. When we substitute the points (-2,-4) into the equation y=-1.5x+b, we get a b value of -7. So the perpendicular line equation is y= -1.5x-7. You can't the parallel line equation with the points (-2,-4) as it is part of the line 2x-3y=8.

How do I do this?? 7-11
mihalych1998 [28]

Answer: slope intercept is y=mx+b form s b= the y intercept and x will just be x and the m is usually a fraction which tells you the slope so what you need to do is mark these points on a line graph draw a line from one to the other and every where it crosses over a point is where you can find the slope and the y intercept giving you the answer
