What is the equation of the line graphed?

The equation of this line is y = 3x - 2

Step-by-step explanation:

In order to find this, start by finding two points on the line. We'll use (0,-2) and (1, 1). From there we start by finding the slope.

m(slope) = (y2 - y1)/(x2 - x1)

m = (1 - -2)/(1 - 0)

m = (1 + 2)/(1)

m = 3/1

m = 3

Now using that, we can plug it, along with a point into point-slope form to get the answer.

y - y1 = m(x - x1)

y - 1 = 3(x - 1)

y - 1 = 3x - 3

y = 3x - 2

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

did u ever get the answers? i need
