sveticcg [70]

Answer:

See attached picture.

Step-by-step explanation:

The equation is in point slope form y - y_1 = m(x-x_1) where m is the slope and (x_1,y_1) is a point.

For the equation y-2 = 23(x+4), graph the point (-4,2). Then from this point count up 23 and over to the right 1.

This is the graph of the line.

Find two positive angles and two negative angles that are coterminal with the given angle and less than 1080 but greater than 72
ivann1987 [24]

Answer:

The correct answer is 450°, 810°, -270° and -630°.

Step-by-step explanation:

According to the given scenario, the calculation of the two positive angles and two negative angles i.e. coterminal is as follows:

The coterminal angles are the angles in which the difference could be 360 degrees or the multiples of 360 degrees

For 90 degrees, the two positive angles are

a. 90° + 360°

= 450°

450° + 360°

= 810°

b. The two negative angles are

= 90° - 360°

= -270°

-270° - 360°

= -630°
