7. A glass blower has a commission to create a hollow glass sphere. The diameter of the sphere will be 18 cm, and the walls will be 1 cm thick. What volume of glass is needed?

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!

And i oop, gurlll he not gonna have no more left .. anna ou
