Question

Write an equation for the line in point/slope form and slope/intercept form that has the given condition.
Slope = 1/2 and passes through the origin.
I kinda forgot how to do this, can someone jog my memory please?

Answer 1

you know your equation will end up in slope intercept form, \[\large y=mx+b\] after deriving it from point-slope form, yes?

Answer 3

We start with point-slope form, with your points (0,0) \[(x_{1},y_{1}) = (0,0)\] and slope \(m=\frac12\).

\[y-y_{1}=m(x-x_{1})\\y-(0)=\frac12(x-(0))\\y=\frac12x\]

Answer 4

@Jhannybean y=1/2x is the point-slope form?

Answer 5

@Jhannybean

Answer 6

y=1/2x would be the point-slope form
y=mx+b would be the slope intercept form, now how do I plug in to make it fit the problem
?
