Write an equation of the line satisfying the given condition.
a) x intercept = 3 y intercept=2
I am really not sure how to start here.
b) vertical line containing (5,1)
Would it be y=5x1?
c) parallel to the line 3x4y=5 and containing the points (3,6) .
I know that the line has to have the same slope as the one about.
d) Find the slope and y intercept of the line 4x6y=3
To find the y value would i plug in zero for the x and solve? And then I can find the slope?

a) isn't the information like being given two points?
(3,0), (0,2)
So just find the slope and you know the yintercept, so
y = mx 2
b) a vertical slope has an undefined slope
It's equation will simply be x = ? (whatever the x of the given point is)
So x = 5
c) real easy
since it has the same slope the new equation must also start with
3x  4y = k, where k is the only number that will differ.
sub in your given point to find k, and you are done
d) rearrange 4x  6y = 3 to the form y= mx + b
6y = 4x  3
divide by 6
y = (4/6)x 3/6
y = (2/3)x + 1/2
