There are eight fewer boys than girls in mrs. davis class. how many boys are in the class?

G-8=B you can't find out B (boys) until you know how many G (girls) there are in Mrs. Davis's class

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!
