Answer 1

Look at the table; for every 3 units that x increases, y goes up also 3, so the change of y with respect to x is 3/3 = 1 , which is the slope.
And the y-intercept is 2, because in the chart when x = 0, y = 2.

So the linear equation is y = x + 2, the slope of this line is 1 and y-intercept is 2.
