Hello! Really, we could finish this problem without knowing the slope or just having one of the given points. However, since they gave us the slope, let's take the easier way.
y = 2x + b To find b, we can plug in one of the points. (it doesn't matter which) 7 = 2(5) + b 7 = 10 + b b = 7-10 = -3
So, the final equation is y = 2x - 3 or answer choice D.
Hope this helps!! let me know if you have ANY questions.
The surface area of a sphere is 4r^2pi, so dividing 100 by 4pi gives a result of 25/pi. Taking the square root and rationalizing the denominator, we have 5sqrt(pi)/pi as the radius of the sphere.
