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