M = (y2-y1)/(x2-x1) so for your question (2--8)/(4--3) = (2+8)/(4+3) = 10/7
Now to find the slope-intercept form (y=mx+b) plug in the slope and a point to find b. I'm going to use point T. So 2 = (10/7)*4 +b => b = 2 - (40/7) = -26/7. So the answer would be y = (10/7)x - (26/7).

Hope this helps!

\frac{6}{9} = \frac{6}{9} ÷ \frac{3}{3} = \frac{6/3}{9/3} = \frac{2}{3}

The cost of 6 hats and 1 scarf is $47. The cost of 3 hats and 2 scarves
Elan Coil [88]

The cost of scarf is $11 and the cost of hat is $6.

<u>Step-by-step explanation:</u>

<u>Let us assume :</u>

  • The cost of hat be 'h'.
  • The cost of scarf be 's'.

<u>Given that, </u>

The cost of 6 hats and 1 scarf is $47

⇒ 6h + s = 47  ------(1)

The cost of 3 hats and 2 scarves  is $40

⇒ 3h + 2s = 40  -------(2)

<u>Solving the equations to find x and y values : </u>

Multiply eq(2) by 2 and subtract eq(2) from eq(1),

  6h + s = 47

-<u>(6h + 4s = 80) </u>

<u> </u>  <u>      -3s  = - 33</u>

-3s = - 33

s =33/3

s = 11

The cost of scarf is $11.

Substitute s=11 in eq(1),

6h + 11 = 47

6h = 47 - 11

6h = 36

h = 36/6

h = 6

The cost of hat is $6.
