Malika and Adrian prepared containers of potato salad at a deli. Each container was
supposed to have a mass of one pound. The manager selected a random sample of
containers prepared by each employee to check the mass of each container. The results
are shown in the table below.

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.

Answer this question, only if you know the answer. 30 points and brainliest!

What number should be added to both sides of the equation to complete this square? x^2-10x=7
