There are no coordinates for an equation like this, you have to just graph the problem. Just try graphing something similar to this (or just include this image). Hope this helps!

The complete question is
"Substitute the values for a, b, and c into b2 – 4ac to determine the discriminant. Which quadratic equations will have two real number solutions? (The related quadratic function will have two x-intercepts.) Check all that apply.
0 = 2x^2 – 7x – 9
0 = 4x^ 2 – 3x – 1
The quadratic equations that have real number solutions are; 4x^2 – 3x – 1, and 2x^2 – 7x – 9.
<h3>What is the formula for Discriminant?</h3>The formula for finding the discriminant is
The solution contains the term which will be:
Real and distinct if the discriminant is positive
Real and equal if the discriminant is 0
Non-real and distinct roots if the discriminant is negative
For the quadratic equation
This equation has two real number solutions.
For the quadratic equation

Answer:
Both triangles are scalene & Both triangles have an obtuse angle.
Step-by-step explanation:
<u>Key skills needed: Triangle recognition, Comparing Triangles</u>
1) We are given those 2 triangles, and we need to see if they are isosceles, scalene, obtuse, and acute.
2) To get this, let's define each thing:
Acute triangle - Means that all the angles in triangle are acute, which means they are less than 90 degrees in measure.
Obtuse triangle - Means that one angle in the triangle is obtuse, which means it is greater than 90 degrees in measure.
Scalene triangle - All the sides of the triangle are different in size/length
Isosceles triangle - 2 sides of the triangle are the same length
3) Now, we can use this to see what both triangles are:
--> Both triangles are not isosceles, they are both scalene. This is because all the sides of each triangle are different in size/length. This makes it scalene.
--> Both triangles are not acute triangles, they are both obtuse triangles. This is since the largest angle in each triangle is clear an obtuse angle (it looks like it is more than 90 degrees). Refer to the image I post as help.
With the observations above: We can say that both triangles are scalene, and both triangles are obtuse triangles.
