A number, n, is added to 15 less than 3 times itself. The result is 101. Which equation can be used to find the value of n?
3n - 15 + n = 101
3n + 15 + n = 101
3n - 15 - n = 101
3n + 15 - n = 101

A.) 3n - 15 + n = 101

Step-by-step explanation:

a) 3n – 15 + n = 101

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
