2. A line goes through the points (8, 9) and (-2, 4).
Scrat [10]

Answer:

Step-by-step explanation:

A line goes through the points (-2, 4) and (8, 9).  We see that x increases by 10 and y increases by 5.

Thus, the slope of this line is m = rise / run = 5/10 = 1/2    (the slope)

Starting with the point slope equation y - k = m(x - h) and substituting 9 for y, 8 for x and 1/2 for m, we get:

y - 9 = (1/2)(x - 8)   (point-slope form)

y       = (1/2)x + 5     (slope-intercept form)

Diano4ka-milaya [45]
If circumference = (2 * PI * radius) then we solve for radius
radius = circumference / (2 * PI)radius = 25.142758 / 22/7 * 2radius =  <span><span>4.00 </span> </span> <span><span> </span> </span>
