Answer:
The slope is 3 and the y-intercept is 2.
Step-by-step explanation:
Slope is 3/1, following the line up 3 and over 1. The line crosses the y-axis at (0,2), so the intercept is 2. The slope-intercept can then be written as y=3x+2.
i think the answer is 18.15
6a + 5a = 11
6a + 5a=
11a
11a = 11
divide both side by 11
11a/11 = 11/11
a = 1
Acute
7² + 9² ? 11²
49 + 81 ? 121
130 is greater than 121, so it is an acute triangle
