A line contains the points (-9,-7) and (13,-19). Find the x-value of the x-intercept. For example, if the x-intercept is (1/3,0), record 0.33.
Write your answer solution rounded to two decimal places.

x = -21.83 or (-21.83, 0)

Step-by-step explanation:

Use the given points to find the slope of the line.

(-9, -7) (13, -19)

Use the slope and one of the given points to solve the point-slope formula

Since you are looking for the x-intercept, set y=0 and solve for x

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
