Answer:
The desired equation is y = x + 8.
Step-by-step explanation:
As we move right from (-2,6) to (4,12), x increases by 6 and y also increases by 6. Thus, the slope, m, m = rise / run, is m = 6/6, or just m = 1.
Start with the slope intercept form y = mx + b. Since m = 1, we now have y = x + b. Subbing 4 for x, 12 for y, we can find b: 12 = 4 + b. Thus, b = 8.
The desired equation is y = x + 8.
Answer:
0.06
Step-by-step explanation:
Arc length = radius * central angle (radians)
central angle (radians)= arc length / radius
central angle (radians)= 60 / 15
central angle (radians)= 4 radians
sector area =(central angle / 2) * radius^2
sector area = (4 / 2) * 225
sector area = 450

4r+2=-26
4r=-28 (subtract 2 from both sides)
r=-7 (divide both sides by 4)
