Which equation is the BEST fit for the data in the graph? A) y = 8x – 75 B) y = 75x – 8 C) y = -8x + 75 D) y = -75x + 8

Most Likely C) y = -8x + 75

Step-by-step explanation:

The scatter plot shows a negative association, so the line of best fit has a negative slope. The eliminates A and B, since their slopes are positive.The highest point is (0,75). Because of this, it is safe to assume that would be the best estimate of the y-intercept.Out best answer is

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
