Answer:
<h2>y - 2 = -4/5(x + 5)</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:

We have the slope m = -4/5 and the point (-5, 2). Substitute:

The answer to the question is x=y/7
The answer to number 16 is 0,15
R= <span><span>√<span><span>x²</span>+<span>y²</span></span></span>
</span> = 16 or <span><span>(<span>x²</span>+<span>y²</span>)</span>
</span> = <span><span>16²</span>
