Question

Pls help me im so confused and i need this done!

Answer 1

Answer:

y = (1/3)x - 9

Step-by-step explanation:

We know that m = 1/3

The function will be in the form:

y = (1/3)x + b

Let's find b by plugging in the coordinates of the point, in the function:

-7 = (1/3)*6 + b

b = -9

Therefore:

y = (1/6)x - 9

Answer 2

Answer:

$y + 7 = \frac{1}{3} (x - 6)$

Step-by-step explanation:

using equation y=mx+c where y is -7, x is 6 and m is 1/3

equate them in the equation to work out c

$y = mx + c$

$- 7 = \frac{1}{3} (6) + c$

1/3 × 6 is 2

$- 7 = 2 + c$

subtract 2 on both sides to find c

$- 7 - 2 = c$

$c = - 9$

The equation is

$y = \frac{1}{3} x - 9$

based out of the following options you have:

i would expand each equation you have and equate it in y=mx+c to see where you have the same equation as above.

It looks like the third option is correct:

writing out the third option

$y + 7 = \frac{1}{3} (x - 6)$

expanding the right side my multiplying. 1/3 × x is 1/3x. 1/3 × -6 is -2

$y + 7 = \frac{1}{3} x - 2$

subtract 7 on both sides so you have y on its own

$y = \frac{1}{3} x - 2 - 7$

$y = \frac{1}{3} x - 9$

so the third option is the same equation as y=1/3x - 9

answer:

$y + 7 = \frac{1}{3} (x - 6)$
