Line QR goes through points Q(0,1) and R(2,7). Which equation represents line QR ?
vodomira [7]
(0,1)(2,7)
slope(m) = (7-1) / (2-0) = 6/2 = 3

y = mx + b
slope(m) = 3
use either of ur points...(0,1)....x = 0 and y = 1
now sub and find b, the y int
1 = 3(0) + b
1 = b

so ur equation is : y = 3x + 1....or 3x - y = -1

Help is it A or B? pls help
Damm [24]

Answer:

f(x)=-(x+8)(x-2)

Step-by-step explanation:

Start by factoring out a -1...

f(x)=-(x^2+6x-16)

Now, we have to find two integers that multiply to get -16 and have a sum of 6:

(-2)*8=-16

-2+8=8-2=6

Using this, we can split 6x into -2x and 8x...

f(x)=-(x^2-2x+8x+16)

Factor  the first and second half separately...

f(x)=-[(x^2-2x)+(8x-16)]\\f(x)=-[x(x-2)+8(x-2)]\\

Since both x and 8 are being multiplied by x-2, we can combine them to get...

f(x)=-(x+8)(x-2)
