Solve the system using substitution. write the solution as an ordered pair. (1 point) show your work for full credit! (2 points)

y = 2x + 11
y + x = 5

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.

Anyone know? is appreciated! will mark brainliest if correct!

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?
