The lateral area of a right circular cone is equal to 120 pi cm^2. if the base of the cone has a diameter of 24 cm , what is the length of the slant height

The lateral area of the cone is given by:
 Al = pi * r * g
 Where,
 r: radius of the base
 g: slant height
 Substituting values we have:
 120 = 3.14 * 12 * g
 Clearing g we have:
 120 / (3.14 * 12) = g
 g = 3.18 cm
 
 The length of the slant height is:
 g = 3.18 cm

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!
