first change it so it looks like
to find the y intercept set
Hi for class i have a hundred problem assignment and out of all the problems a few have stumped me i know there not difficult but i am having trouble, i just want to do really good on this assignment , if you can help thanks.
1.)The business opened with a debt of $4300. After 2 years, it accumulated profit of $4600. Find the profit as a function of time , knowing the profit function is linear.
2.)) Find the slope and the y-intercept of the line
3.)The equation of the line with slope that goes through the point can be written in the form where is
4.)Find the - and -intercepts of the graph of the equation
again thank you so uch of you can help

(a) If the function is linear, then it means that the profit each year is constant. So that's per year. After t years, then, the profit will be .
(b) In a similar way, this time .
2.)) Find the slope and the y-intercept of the lineThis is now in the form , so the slope is , and the intercept is .
The value of is (the slope). If you want the value of as well, plug in the values of and that you know (and this value of ), to get:3.)The equation of the line with slope that goes through the point can be written in the form where is
Can you solve this equation now to find ?
The -intercept is where has the value . So that's .4.)Find the - and -intercepts of the graph of the equation
For the -intercepts (there are two), give the value :
Can you complete this quadratic equation?
