Question 674787: what is the slope intercept for (2 , 4), perp to y = -2/7x-5

You can put this solution on YOUR website!
The slope of y = %28-2%2F7%29x-5
is -2%2F7
...
A perpendicular line will have a slope of negative inverse, which is 7%2F2
...
Using (2, 4)
y - 4 = %287%2F2%29%28x-2%29
y - 4 = %287%2F2%29x+-+%287%2F2%29%282%29
y - 4 = %287%2F2%29x+-+7
y = %287%2F2%29x-+7+%2B+4
highlight_green%28y+=+%287%2F2%29x-3%29
