<h3><u>Explanation</u></h3>

Convert the equation into slope-intercept form.

$y = mx + b$

where m = slope and b = y-intercept.

What we have to do is to make the y-term as the subject of equation.

$9x - 3y = 15 \\ 9x - 15 = 3y \\ \frac{9x - 15}{3} = y$

Simplify

$\frac{9x}{3} - \frac{15}{3} = y \\ 3x - 5 = y \\ y = 3x - 5$

From y = mx+b, the slope is 3.

<h3><u>Answer</u></h3>

$\large \boxed {slope = 3}$

Which equation represents a linear function?

quester [9]

Answer:

Step-by-step explanation:

y = 9 - X is a linear function; x is to the first power.

y = x2 + 1 does NOT represent a linear function; it's a quadratic function.

y=x² + 5 does NOT represent a linear function; it's a quadratic function.

y = [xl - 9 does NOT represent a linear function; it's an absolute value function. This function has two halves, each of which is a linear function.

But the best answer here is that y = 9 - X is a linear function; x is to the first power.
