Math Advanced Practice Questions & Answers 2024. The estimated total cost, y, of a chid's toy is partially based on the number of batteries used, x. The cost of one battery is $0.75. The toy itself costs $12. Which equation represents the situation? y = 12x + 0.75 y = 0.75 + 12 y = 12x - 0.75 y = 0.75x - 12 - ANSWER y=0.75x + 12 Which linear equation has a slope of 3 and a y-intercept of -2? y = 3x + 2 y = 3x - 2 y = -2x + 3 y = -2x - 3 - ANSWER y = 3x - 2 Which statements accurately describe how to determine the y-intercept and the slope from the graph below? To find the y-intercept, begin at the origin and move horizontally to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation . = y2-y1/x2-x1 To find the y-intercept, begin at the origin and move horizontally to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation .= x2-x1/y2-y1 To find the y-intercept, begin at the origin and move vertically to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation .= y2-y1/x2-x1
