Linear equations. write the standard form of an equation of the
line that passes through the given point and has the given
slope.

The standard form of an equation of the line that passes through the given point having slope is

Step-by-step explanation:

The standard form of an equation of the line that passes through the given point ( and having slope m is

another form of an equation of the line that passes through the given point ( and having slope m is

   y=m 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°
