Find the slope of a line through the points: (1,6) and (2,8).
Nataly_w [17]
So, for the slope, you’ll have to do rise over run (or change in y over change in x) so it’ll be 2/1 so your slope will be 2

And the y intercept can be found if you compare the equation give to y=mx+b, this is because b is the y-intercept value which is those equation will be 2.

22.  What is an equation of the parabola with vertex at the origin and focus (−4, 0)?
miv72 [106K]
The correct answer for the question shown above is the second option (Option b), and the option cwhich is:

 b) x = -1/16y^2
 c) y=-1/16x^2

 
The explanation is shown below:

 
The focus of a parabola is (h,k+1/4a), then, you have:

 h,k= (0,0)
 1/4a=1/4(-1/16)

 Then, you obtain:

 1/4a=-4

 Therefore, the focus of the equation of the parabola x = -1/16y^2 and the parabola y=-1/16x^2 <span>is F(0-4)
</span>
 So, as you can see, the correct answer is the options mentioned before, the option b and the option c.
