Alex drives at a speed 75 mph. Write a function showing the dependence of the distance (D) covered by Alex in t hours. Find the domain and range of the function.

D) the x-intercept represents adam's commission pay when he had zero total sales

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
