Write the slope-intercept equation for the line that passes through (14, -2) and is perpendicular to 7x – 10y = 18

Question

anonymous · Answer

so perpendicular lines : m1 * m2 = -1

anonymous · Answer

can you find the slope of the requested line now ?

anonymous · Answer

To be honest, I am really lost on this problem. I have tried to work it a bunch of different ways, but i cant figure it out, and this is a practice question, so I know my test will be hard

anonymous · Answer

ok.. so first find the slope of 7x – 10y = 18

anonymous · Answer

call it m1.. then you know that your line (lets call it's slope m2) will satisfy m1 * m2 = -1 (since they are perpendicular)
