Full solution

Q. The y y -intercept of the graph of y=7x+140 y=-7 x+140 is located at (0,c) (0, c) . What is the value of c c ?
  1. Determine y-intercept: To find the y-intercept of the graph of the equation y=7x+140y = -7x + 140, we need to determine the value of yy when x=0x = 0.
  2. Substitute x=0x=0: Substitute x=0x = 0 into the equation y=7x+140y = -7x + 140 to find the y-intercept.\newliney=7(0)+140y = -7(0) + 140\newliney=0+140y = 0 + 140\newliney=140y = 140
  3. Identify y-intercept point: The y-intercept of the graph is the point where the line crosses the y-axis, which occurs at x=0x = 0. Therefore, the y-intercept is at the point (0,c)(0, c), where cc is the value of yy when x=0x = 0.
