Jude incorrectly simplified the expression (1/2)^2 × 1/2 × (1/2)^3 as shown below

(1/2)^2 × 1/2 × (1/2)^3 = (1/8)^6 = 1/262,144
describe the mistake she made.

When you are multiply any common x that has exponents, you only add the exponents and do not change the base number like shown below with x:, she should gave gotten: 



Here is the general example:
 

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!
