Write an equation for the line in point/slope form and slope/intercept form that has the given condition.
Help?..
4. Slope = 3/2 and passes through the origin.
5. xintercept = 4 and yintercept = 3
6. Passes through (3, 2) and is parallel to 2xy=4
7. Passes through (1, 1) and is perpendicular to y= (5)/(2)x+3

as you know, slope is ∆y/∆x
so, for any point (x,y) on the line containing (h,k) with slope m,
m = ∆y/∆x = (yk)/(xh)
or, as some like it,
y = m(xh) + k
So, for #6,
2xy = 4
y = 2x4, so
slope is 2, so
(y2) = 2(x3)
y = 2x  4
Do the others the same way. Com eon back if you get stuck. Be sure to show how you got there.
