how do you find the slope if only two points are given: x intercept = -1/2 and y intercept = 4 write an equation in point slope and slope intercept?

Question

i get how to write the equation i just dont know how to get the slope ):

anonymous · Answer

You need only 2 points for a line and you have them.  Slope = m = (y2-y1) / (x2-x1).

anonymous · Answer

but i only have two points, how would i plug it in that equation ?

anonymous · Answer

First, identify what your points are.  Hint: each point will have either a y or x value equal to zero, from the definition of an intercept.  Then, just call one point P1 or 1 and the other P2 or 2.  Take the corresponding x and y from P1 and that will be x1 and y1.  Similar for the other point.

oh!! so it will be (-1/2, 0) and then (0,4)?

anonymous · Answer

yes, you're getting it.
