Can someone me find what's the value ?

V=pi r^2 h
pi=3.14
radius squared= 8^2
height=12
plug it in and multiply to get 2412.743158

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!
