Help, I really need help and I've been stuck on this one ^^^
Lostsunrise [7]

Hey there! :)

Let's put all of our facts down first. We know that slope-intercept form is y=mx+b , where m=slope & b is the y-intercept.

So, if we're given the slope and y-intercept, then we can very simply plug those values into slope-intercept form!

Our slope is 4 and our points are (0, -1).

y = mx + by = (4)x + (-1)

Get rid of our parenthesis.y = 4x - 1

So, our equation of the line that passes through (0, -1) and has a slope of 4 is y = 4x - 1

~Hope I helped!~

There's a simple formula for the area of an ellipse:  pi*a*b, where a and b are , half the lengths of the long axis and the short axis respectively.

Here, A = pi*(12 ft)(4 ft) = 48 pi ft^2, or about 150.8 ft^2.
