HELP EXPERT: I'LL GIVE BRAINLIEST IF YOU EXPLAIN THE ANSWER:

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.
