Question

Find the slope-intercept 
(y = mx + b) form of the line satisfying the given conditions.
Parallel to y = -2x, passing through (0,1)

sburchette · Answer

In order for the line to be parallel to y=-2x, it must have the same slope. The point (0,1) happens to be the y-intercept. So from this information, we know m and b. The equation of the line is$$y=-2x+1$$

anonymous · Answer

y-y1=m(x-x1)
m=0, y1=1 and x1=0
y-1=-2(x-0)
y-1=-2x
Slope-intercept form is y=mx+c
y=-2x+1

ummmm i dont get it iam sorry

anonymous · Answer

Are you familiar with the equation 
$$m=\frac{y_2-y_1}{x_2-x_1}$$

anonymous · Answer

And this is the same thing as $$y_2-y_1=m(x_2-x_1)$$

anonymous · Answer

And like @SBurchette  was saying earlier parallel lines have the same slope. So the slope of a line parallel to y=-2x is -2 because m here is -2.

i was working with that a little last week

And it's okay if you don't understand but what exactly is it that you don't understand?

Did you figure it out @compaqangel0205 if you want to start over we can do so in another question :)
