The height of a triangle is 4 m more than twice the length of the base. the area of the triangle is 35 me^2. find the height of the triangle
If the discriminant of a quadratic equation is equal to -8, there are two complex roots.
<h3>Discriminant of a quadratic equation</h3>
The discriminant is used to determine the nature of quadratic equations.
The formula for calculating discriminant is given as:
D = b^2 - 4ac
If the discriminant is negative, it means that the nature of the solution will be a complex number.
Hence if the discriminant of a quadratic equation is equal to -8, there are two complex roots.

A. The slope of a flat line is smaller than the slope of a steep line with a positive slope.
D. A negative slope means that the line moves down from left to right.
E. The slope of a flat line should be exactly 0.
<h3>How to identify a Slope?</h3>
The general slope intercept form equation is;
y = mx + c
where;
m is the slope(rate of change)
c is the y-intercept (value of y when x = 0)
Now, we can say the following about slopes;
- If the slope is is zero, then the line is flat.
- If the slope is positive, then the line is increasing.
- If the slope is negative, then the line is decreasing.
- A steep line has a high slope.
Looking at the options, we can say that options A, D and E are correct.
