How do you find the value of "b"?
I'd like to help (and I'm sure others would as well), but (a) there are bits cut off the picture, (b) the picture is sideways which makes it hard to read, and (c) you'll get better responses with a better thread title.
3. Find the gradient between -2,0 and 6,6.
U know the two lines are perpendicular so the gradient between 3,b and 6,6 will be the negative reciporcal of the gradient u found out previously
U can then substitute 6,6 into y = mx +c To find the line equation
Then substitute 3 into the equation to get b
