Robert Jones’s charge account statement showed a previous balance of $1,342.75, a finance charge of $252.82, new purchases of $1,946.50, and a payment of $2,400.00. What is his new balance?

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!

The correct answer would be shape of function b = 2× slope of function a.
