What is the equation of the line in slope intercept form using these points?

Mathematics

deff fn [24]3 years ago

Answer:

y = -x - 1

Step-by-step explanation:

1. The slope-intercept form of any linear equation is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.

2. To find the slope given two points, we can use the formula \frac{y_2-y_1}{x_2-x_1} and plug in the corresponding variable.

  • \frac{5-(-2)}{-6-1}
  • \frac{5+2}{-7}
  • \frac{7}{-7}
  • -1

3. Okay, so the slope is -1x or just -x. This means that the equation looks like this so far: y = -x + b

4. To find b, the y-intercept, we can take the equation of b = y_1 - m * x_1 and plug in the values!

  • b = -2-(-1)*1
  • b = -2 + 1 * 1
  • b = -1 * 1
  • b = -1

5. Now that we have our y-intercept and slope, let's plug in those values and find the equation!

  • y = -x - 1

Therefore, the equation of the line is y = -x - 1. I hope this helped you!

Answer:

discriminant =0

1 real root

Step-by-step explanation:

The discriminant is b^2 -4ac  

when the equation is written in the form  ax^2 +bx+c

f(x) = 3x^2 +24x+48

a = 3   b = 24 and c =48

discriminant = 24^2 - 4(3)*(48)

                      =576-576

                        =0


If the discriminant >0  we have 2 real roots

if discriminant = 0  we have 1 real root

if discriminant <0 we have 2 complex roots
