Need help!! What is the slope of the line through (2,-2) and (9,3)?

In-s [12.5K]

Finding the slope using two points:

The formula for slope is

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In this case...

$y_{2} =3\\y_{1} =-2\\x_{2} =9\\x_{1} =2$

^^^Plug these numbers into the formula for slope...

$\frac{3 - (-2) }{9 - 2}$

A) $\frac{5}{7}$

^^^This is your slope

Hope this helped!

Which of the following is true of the discriminant for the graph below?

Sonbull [250]

Answer:

Option C. It is zero

Step-by-step explanation:

The graph represents a quadratic equation

The quadratic equation has the form ⇒a x² + b x + c

The discriminant of the quadratic equation is D = b² - 4ac

From the discriminant of the quadratic equation, we can know the type of roots of the quadratic equation.

If D > 0 ⇒ Two real roots.
If D = 0 ⇒ one real roots
If D < 0 ⇒ Two imaginary roots.

The roots of the quadratic equation are the x-intercepts of the function.

As shown at the figure, the quadratic equation has only one point of intersection with the x-axis

So, the function has only one root ⇒ D = 0

So, the discriminant of the quadratic equation = 0

The answer is option C. It is zero
