What is the answer or solution 9s/2=45

S would be equal to 10. We’d multiply 45 by 2 to get the 90 then divide by 9 to isolate it

9s/2=45
9s=90 (Multiply both sides by 2)
s=10 (Divide by 9 on both sides)

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!
