She paid 1247$ with tax

Step-by-step explanation:

7.5% of 1160$ is 87$ you then add 87 to 1160$ to get 1247$

its $1247

explanation: I had it wrong the first time cause I read it as 1660 instead of 1160 but. you do 1160×.075 yo get your sales tax which is 87 dollars. you then add that to your total.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
