Answer:

2/3

Step-by-step explanation:

How many equations here have a slope of 3?

We need to find them and count them.

3y = 9x + 3

1st. y = 3x + 1 has slope 3

2nd ... x(x+3) = 0 is not a line

3rd. 3x + y = 0 y = -3x

4rth. x^2 + 3 = 0 is not a straight line

5th y - 3x = 0 is y = 3x yes has slope 3

Only 2 equations have a slope of 3. 2 out of 5 total but...

But there are only 3 equations here that are straight lines

so 2 out of 3

Write an equation for the line described. give the answer in standard form. through (3,1),m=-6

goblinko [34]

$\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{1})~\hspace{10em} slope = m\implies -6 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-1=-6(x-3) \\\\\\ y-1=-6x+18\implies y=-6x+19$

bearing in mind that

standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

then we'd end up with 6x + y = 19.
