Answer:
√(23)
Step-by-step explanation:
The Pythagorean Theorem is a² + b² = c²
so...
a = 7
b = 3
7² + 3² = c²
14 + 9 = c²
√(23) = c

<span>x-intercept is when y = 0 
0 = -1/2x - 2 
1/2x = -2 
x = -4 
x-intercept = (-4,0) 
y-intercept is when x = 0 
y = -1/2(0) - 2 
y = -2 
y-intercept = (0, -2) 
(note that in the form y = mx+b, b is the y-intercept, so in y = -1/2x - 2, -2 is the y-intercept) 
Now to graph, simply plot these two points (-4, 0) and (0, -2) and draw a line between them. 
Best of luck!</span>
