Okay. Do you have any idea where to start?

Hint : if you have two straight lines and they are perpendicular Then M1 x M2 =1 when M = Slope .

Here's the hint: The slope of a line perpendicular to another is the negative reciprocal. If the slope is m, then the slope of the perpendicular line is 1/m. Does that make sense?

@inkyvoyd It sort of does... I understand that part but I don't get what comes next

Well, you are given a line. You want to know the slope of a line perpendicular to it. With the line you are given, what is the slope? Whatever the slope is, the slope of a line perpendicular to it is 1/m where m is the slope.

@inkyvoyd The slope is already given so I did the reciprocol. So instead of the basic problem of (5,7); y= 1/3x + 2 ... So far I have 3x (+ or  somthing) I need to figure out the something

Wee, you need to be careful to take the negative. You have a slope m=3. and you have to condition that (7)=(3)(5)+b (I just substituted y, m, and x into y=mx+b, the equation of the slopeintercept line)

@inkyvoyd SO my final answer would be y= 3x + 9 ?

No. How did you get that answer?

@inkyvoyd Ack I knew it I'm a dumbarse I got it because 3 is the slope and using y= mx+b And 3 times 3 (5 2) is 9

uhh, I'll work it out step by step y=mx+b m=3 (x,y)=(5,7) (7)=3(5)+b 7+15=b b=22
