Answer:
Step-by-step explanation:
a line parallel to the equation would have the same slope (7/8)
so what we know so far is
y = 7/8x + b
since it has to go through point C (-4, 8)
we’ll plug in those values for x and y (x = -4, y = 8)
8 = 7/8(-4) + b
8 = -28/8 + b
8 = -3.5 + b
b = 11.5
so the equation is
y = 7/8x + 11.5
If the center is at (0, 0) and the vertex is at (20, 0), then the distance, a, is the length from the center to the vertex, 20. The distance from the center to the focus is c. The distance from the center to the focus is 16, so c = 16. The formula we use to find the focus is
. We have our c value and our a value, so we will sub in those to find b.
and 256 = 400 - b^2. -b^2 = -144, so b = 12. There you go!
I believe it is C hope it helps
Answer:
Look for the y-intercept where the graph crosses the y-axis. Look for the x-intercept where the graph crosses the x-axis. Look for the zeros of the linear function where the y-value is zero.
