Someone please help me with this, im not really good at math and i dont understand this...

Step-by-step explanation:

We need the equation of the line in the form:

where m is the slope of the line and b is the y-intercept.

y-intercept: the point where the line touches the y axis.

In this case that point is 6. So b = 6

Slope:

is the rate of change between the y-coordinate and the x-coordinate on the graph of the line.

To find the slope we need two points where the line crosses, I will take the points:

and

where we name the coordinates as follows:

and use the slope equation:

substituting our values:

and so, gathering the information we find we can define the equation of the line:

its the fourth option
