Answer:
D = 141
Step-by-step explanation:
The given quadratic equation is
.
It is required to find the value of the discriminant. The value of discriminant of any quadratic equation is given by :

Here, a = 5, b = 9 and c = -3
On plugging all the values, we get :

So, the value of discriminant for y is 141.
Answer:
slope = 1/2
Step-by-step explanation:
slope = y2-y1 / x2-x1
1 - -2 / 4 - -2 = 3/6 = 1/2
or think of it this way. for every 1 step up you take 2 steps to the right to stay on the line. 1/2
The answer is letter choice B
