3. ### How do you find the equation of the lines that pass through the point (-3,-4) and are a distance of root 10?

If m is the slope of the line, then the equation that passes through (-3, -4) is y+4 = m (x+3) or y = m (x+3)-4 The condition that a point (x,y) is at a distance sqrt(10) from (2,1) is (x-2)^2 + (y-1)^2 = 10 Replacing y from above and expanding...

8. ### What is the answer to this math question?

First, you have to find the equation of that line. (x + 8)/(6+8) = (y-8)/(-10-8) (x+8)/14 = (8-y)/18 (x+8)/7 = (8-y)/9 9(x+8) = 7(8-y) 9x + 72 = 56 - 7y 9x + 7y = -16 y = 1 => 9x + 7 = -16 9x = -23 x = -23/9, so t = -23/9

10. ### The equation of the line that goes through the points 1,-7 and 10,6 find m and b?

ok all you got to do is put in slope intercept form. find the slope which in this case...b to double check you take change in y over change in x. 6--7 =13 10 -1 = 9 which makes 13/9 then plug it in to find the y intercept.
