Why do equivalent ratios form a straight line when graphed? The vertical distance between points is constant, and the horizontal distance between points increases with each point. The ratio of the change in y-values to the change in x-values is equivalent for any two points in a graph of equivalent ratios. The horizontal distance between points is constant, and the vertical distance between points increases with each point. The y-values of equivalent ratios increase at a constant rate, and the x-values decrease at a constant rate. HALP!

Which of the following would be a good name for the function that takes the weight of a box and returns the energy needed to lift it?

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
