Write the quadratic equation whose roots are 1 and −5, and whose leading coefficient is 4.
jarptica [38.1K]

Answer:

Standard Form: y = 4(x-1)(x+5)

Step-by-step explanation:

4 is the leading coefficient, so it should go in front. When making a standard quadratic equation, you must do the opposite for each of the roots (negative to positive, positive to negative.)

if you’re asking for a general form quadratic equation, then sorry, I am unable to help you with that :(

Find the slope of the line through each pair (1,-19),(-2,-7)
expeople1 [14]

hello i see that no one has answered your question yet well im here to help:)

(1,-19),(-2,-7)

so here one way you can find the slope

i usually always use this to help me to keep it in order

------------------

(X1,Y1)(X2,Y2)

   X2-X1

   Y2-Y1

use this and your garanteed to get the right answer everytime

------------------

X = -2 – 1 = -3

Y = -7 – -19 = 12

once you do that you divide if possible

12/-3

which gives you -4

so your answer is -4

its really not hard you just got to get use to it

hope it help you:)
