Which expression is equal to sina? A) sin0
B) cos0
C) cos(90°-b)
D) sin 90°- sin b

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula, equation, to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.

Give all possible names for the line shown. calculation tip: lines can be written with either point first.

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2
