Aline has a slope of 2 and a y-intercept of 10. what is its equation in slope-intercept form?

What is 32+4 x (16 x 1/2) -2 show your work}

Last one and the bottom answer choice is y=(x-4)^2+1 you guys!

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
