4.2.B- If the alternator-to-engine drive ratio is 2.15 to 1, what rpm will the alternator have when the engine is idling at 500 rpm? Hint: Use a direct proportion.
The alternator will have rpm when the engine is idling at 500 rpm.
(Type a whole number or a decimal.)

Iwould like to think so. what’s the question you need with?

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!
