Step-by-step explanation:
we don't see all possible answer options.
but it does not matter.
the line is clearly
y = 2x - 6
why ?
the slope is always the factor of x.
and the slope is defined as ratio of "y coordinate change / x coordinate change".
and we can clearly see, for every change in x by +1, y changes by +2. zu, the slope is 2/1 = 2.
and when x = 0, the graph shows us the y-intercept with y = -6.
hence the above mentioned equation.
