(-3, -2) is the vertex.
You can find this by plugging into -b/2a to find the x value and using the x value to find the y value.
And another spot on the vertex would be (0, 16), which is the y intercept.

<span>To find the slope, you divide the difference of the y-coordinates of a point on a line by the difference of the x-coordinates. It is expressed as:
slope = (y2 - y1) / (x2-x1)
slope = 8-(-7) / 4 - 4
slope = 15 / 0
slope = undefined <------ SECOND OPTION
The line should be vertical where the slope is undefined. Hope this answers the question. Have a nice day.</span>
Answer:
1. 7.6 = c
2. 45 = c
Step-by-step explanation:
1. 3^2 + 7^2 = c^2
9 + 49 = c^2
58 = c^2
square root both sides = 7.6 = c
2. 27^2 + 36^2 = c^2
729 + 1296 = c^2
2025 = c^2
square root both sides
c = 45
