A line intersecting the x-axis at (5,0) has slope 2. Find the y -intercept.
General format of a straight line: y = mx + c , where m = slope, c = vertical intercept or y intercept. m = slope = 2 y = 2x + c. Since the line passes through (5,0), means when x = 5, y=0 y = 2x + c 0 = 2*5 + c 0 = 10 + c 0 -10 = c -10 = c. c = -10 Therefore y intercept is = -10. I hope this helps.
