Hi can someone please help me with this question I've been stuck on it for so long!!

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.

Is it greater than or less than7*3_9*2

If two angles are complementary, which is the sum of their measurements? a. 45o b. 90o c. 120o d. 180o
