Question

What is the x-intercept of the line y +2 = 3(x + 1)​

Answer 1

Explanation:

y+2=3(x+1)

y+2=3x+3

y+3x+5

y=mx+b

m=x-intercept

x-intercept=3

Answer 2

(-1/3, 0)

Explanation:

You want the x-intercept of the line y +2 = 3(x + 1)​.

X-intercept

The x-intercept is the point where the graph intersects the x-axis. The value of y is zero there. It can be found by solving the equation for x with 0 substituted for y.

0 +2 = 3(x +1) . . . . . substitute y=0 in the given equation

2/3 = x +1 . . . . . . . . divide by 3

-1/3 = x . . . . . . . . . . subtract 1

The x-intercept is x=-1/3. The point there is (-1/3, 0).
