Question

17. What is the slope of the line given by the equation
2x + 9y = -18?
A.-2
B.-
$\frac{9}{2}$
c. -
$\frac{2}{9}$
D.2
E.9​

Answer 1

Answer:

slope = - $\frac{2}{9}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

2x + 9y = - 18 ( subtract 2x from both sides )

9y = - 2x - 18 ( divide all terms by 9 )

y = - $\frac{2}{9}$ x - 2 ← in slope- intercept form

with slope m = - $\frac{2}{9}$
