Q. If y=1.8x+1 is graphed in the xy-plane, which of the following characteristics of the graph is displayed as a constant or coefficient in the equation?Choose 1 answer:(A) y-intercept(B) x-intercept(C) Slope(D) The value y approaches as x decreases
Identify constant term: Identify the constant term in the equation y=1.8x+1.The constant term in the equation is +1. This term does not depend on the value of x and is added to the value of 1.8x for all x.
Significance in graph: Determine the significance of the constant term in the context of the graph.The constant term in an exponential function like y=1.8(x)+1 represents the vertical shift of the graph. In this case, the graph is shifted up by 1 unit.
Relate to characteristics: Relate the constant term to the characteristics of the graph provided in the choices.The constant term affects the y-intercept of the graph. The y-intercept is the point where the graph crosses the y-axis, which occurs when x=0. Plugging x=0 into the equation y=1.8(x)+1 gives y=1.8(0)+1, which simplifies to y=1+1, or y=2. This shows that the y-intercept of the graph is y0, and it is directly given by the constant term y1 in the equation.
