Answer:

y+2=1/2(x-8) or y+4=1/2(x-4)

Step-by-step explanation:

Okay, so point slope form is y-y1=m(x-x1). So you substitute y1 with -2 or 8 and x1 with 8 or 4.

Slope is (-2-(-4))/(8-4), which is 2/4, or 1/2. Plug that into m.

Answer:

y+2 = 1/2(x-8)

Step-by-step explanation:

We need to find the slope

m = (y2-y1)/(x2-x1)

   = (-4--2)/(4-8)

   = (-4+2)/(-4)

  = -2/-4

  = 1/2

We know the slope and we know a point, so we can use point slope form

y-y1 = m(x-x1)

y--2 = 1/2(x-8)

y+2 = 1/2(x-8)


If we had used the other point

y--4 = 1/2(x-4)

y+4 = 1/2(x-4)

What is the equation of the line shown in this graph
prisoha [69]
Slope = (2+4)/(1-4) = 6/-3 = -2
passing thru (1.2)
y = mx + b
b = y - mx
b = 2 - (-2)(1)
b = 2 + 2
b = 4

I didn’t study and it’s 2 am pls help
AlexFokin [52]

Answer: 7. g = -50, 8. f= 340/6 9. 3 10 .125

Step-by-step explanation:#7 g(3): 4(3)^2 +6 =12^2 +6 = 1444=6= 150. We divide 150 by 3 giving us -50.  #8We start by putting f(6): -3(6)^2 -4(6) +8. We use PEMDAS. -18^2 -24 +8 = _324-24+8 F= 340/6 #9 g(15) = Square root of 15-6=9 and the square root of 9 is 3, therefore, the answer is 3. #10 h (x) = 2^x we plug -3 to 2^-3. It is a negative number and it gives us .125 or 12.5
