Ken thinking of a number nine more than the product of four and the number is 73 find kens number

Goal: to find the number 
Define: x = number 
Sentence: seventy three equals nine plus four times the 
Equation: 73 = 4x +9 
Solve: x = 16

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!
