The slope of the line below is -4. Write the equation of the line in point-slope form, using the coordinates of the labeled point. Do not use parenthesis on
the y side. (-2, 2)

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
