Answer:

y =  \frac{1}{6} x

Step-by-step explanation:

The equation of a line can be written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

\boxed{gradient =  \frac{y1 - y2}{x1 - x2} }

Using the above formula,

m =  \frac{1 - ( - 1)}{6 - ( - 6)}  \\ m =  \frac{1 + 1}{6 + 6}  \\ m =  \frac{2}{12}  \\ m =  \frac{1}{6}

Substitute the value of m into the equation:

y =  \frac{1}{6} x + c

To find the value of c, substitute a pair of coordinates.

When x=6, y=1,

1 =  \frac{1}{6} (6) + c \\ 1 = 1 + c \\ c = 1 - 1 \\ c = 0

Thus, the equation of the line is y=⅙x.

The table shows three unique functions.
Dovator [93]

Answer:

<h2>All three functions have a y-intercept.</h2>

Step-by-step explanation:

The table is attached, there you can observe functions f(x), g(x) and h(x).

Remember, when x = 0, it represents a y-intercept. So, we can deduct that all three functions have y-intercept, (0,1) for f(x), (0, -1/2) for g(x) and (0,-5) for h(x).

Also, x-values represent domain values, however, in this case, we can't say that all three function have the same domain values, because we don't know the domain defintion for each of them to determine such thing.

Additionally, in the table you can observe that f(x) has the greatest maxium, so the second choice is also false. And neither function has x-intercept.

Therefore, the only right answer is the third choice.

Find the derivative of g(t)=t2+5t at t=7 algebraically.
Elanso [62]

The power rule applies to each term.

... (d/dt)(t^n) = n·t^(n-1)

... g'(t) = 2t +5

... g'(7) = 2·7 +5 = 19
