Answer:
= 0
Step-by-step explanation:
-3 = x^2 + 4x + 1
0 = x^2 + 4x + 4
a = 1
b = 4
c = 4
plug the numbers into the equation to find the discriminant value...
4^2 - 4(1)(4)
16 - 16 = 0
therefore your answer is 0

Answer: 1/4
Step-by-step explanation:
First, we have to rearrange the given equation so that it results in a y=mx+b equation. To do this we can add -1/2x on both sides to remove it from the left side.
(+1/2x)-1/2x + 2y = 7(+1/2x)
2y = 1/2x +7
Now we can divide by 2 on both sides to isolate the y.
(2y)/2 = (1/2x +7)/2
y = 1/4x + 3.5
The slope is 1/4 :)
