to get the equation of a line, we simply need two points, say for the Red one ... notice in the graph the lines passes through (0,2) and (-1,6), so let's use those
now, for the Blue one, say let's use hmmm it passes through (0,2) and (1.6)
The answer is y = 3/4 x + 2
<em>Explanation:</em>
Basically, the formula for a linear equation is y = mx + b
b = y-intercept
mx = slope
slope = rise/ run (pos.)
it can also be fall/ crawl (neg.)
In the graph the line meets at the y-int. at 2, the line rises 3 and goes right 4 each time.
Answer:
the bottom one 42.061
upper one 49/2pi = 76.969
Step-by-step explanation:
the bottom one
14^2 - 49pi = 42.061
upper one, put the shaded parts together and that forms a semicircle
49/2pi = 76.969
