Answer:
Step-by-step explanation:
So we know that the slope is 2 and the lines passes through the point (-5,1).
We can use the point-slope form. The point-slope form is:
Where m is the slope and (x₁, y₁) is a point.
So, let's substitute 2 for m and (-5,1) for (x₁, y₁), respectively. Therefore:
Simplify:
Distribute the 2:
Add 1 to both sides:
So, the equation of our line is:
Answer:
Step-by-step explanation:
The given quadratic equation is:
Comparing it with the standard form of Quadratic Equation , we get:
a = 3, b = -9 and c = 1
Discriminant = b² - 4ac
D = (-9)²-4(3)(1)
D = 81 - 12
D = 69
