In slope intercept form this is equal to y=3/2x+8. If you want it in decimal form it would be y=1.5x+8.
The most prevalent age group reporting stage fright was between 35 and 45 years of age. Wind instrument players were the group most involved (22% of those reporting stage fright).
-4x + 7y = 9 ⇒ -4x + 7y = 9 ⇒ 8x - 14y = -18
2y = -5x - 22 ⇒ -5x - 2y = 22 ⇒ <u>-35x - 14y = 154</u>
<u>43x</u> = <u>-172</u>
43 43
x = -4
-4x + 7y = 9
-4(-4) + 7y = 9
16 + 7y = 9
<u>- 16 - 16</u>
<u>7y</u> = <u>-7</u>
7 7
y = -1
(x, y) = (-4, -1)
