2x+9= 32
2x= 32-9
2x= 23
x= 23:2
x= 11.5
The Y intercept is where the function passes/ intercepts the y axis. On a table, it is where x is 0, in this case the y intercept is -20. The slope is found by change in y over change in x. So choose any two coordinates to find change. 10/5=2. So your answer is A.

A whole pizza has 8 slices. 1/4=25%. 25% of 8 is 2.
Answer:
70% in favor of building a new playground
<em>3500 (</em><em>in favor</em><em>) + 1500 (</em><em>against it</em><em>) = 5000 (</em><em>total number votes</em><em>)</em>
<em />
<em>3500 (</em><em>in favor</em><em>) 1500 (</em><em>against it</em><em>)</em>
<em> ------------------- = 0.7 / 70% ------------------- =0.3 / 30%</em>
<em>5000 (</em><em>total</em><em>) 5000 (</em><em>total</em><em>) </em>
In standard form, slope is always the negative of the x coefficient over the y coefficient.
If you dont want to have that memorized, you can use algebra to get the equation of the line into slope-intercept form (y=mx+b)
Set it equal to y
2x - 5y = 6
2x = 5y + 6
2x - 6 = 5y
(2/5)x - 6/5 = y
Now it is in slope intercept form. In slope intercept form, the coefficient multiplying with x is the slope of the line. Therefore, the slope equals 2/5.
