IHave Like 20 Of These Same problems..
Can You Help Me With These?..
1. Slope = 3/2 and passes through the origin.
Wiriting equations..
2. xintercept = 4 and yintercept = 3
3. Passes through (3, 2) and is parallel to 2xy=4
4. Passes through (1, 1) and is perpendicular to y=(5/2)x+3

1. given slope, passes through origin:
y=mx
here m=3/2
2. given xintercept=a, yintercept=b
y=(b/a)x + b
here a=4, b=3
3. Given point (x0,y0) on line and slope m:
yy0=m(xx0)
(x0,y0)=(3,2)
m=2 (coefficient of x in given line)
4. Given point (x0,y0) on line, and perpendicular to slope m
Given slope m=5/2,
slope of perpendicular m'= 1/m = 2/5
(x0,y0)=(1,1)
Line: (yy0)=m'(xx0)
Slope m = 2
