If the radius of a cylinder is doubled and the height is tripled, what happens to the volume? a) it is multiplied by 6. eliminate b) it is multiplied by 12. c) it is multiplied by 18. d) it is multiplied by 32.

A. Imagine the circle has a radius of 3 and height of 9. 3 x 9 = 27/3 is 9. If radius is doubled that’s 6 and height is tripled would make it 27. So 6 x 27 is 162 divided by 3 is 54 and 9 x 6 is 54

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!
