The slope of the line that passes through the points (-3, 5) and (1, 7) is slope = (7 - 5)/[1 - (-3)] = 2/4 = 1/2

The translation 2 units left of the graph of y = |x| is y = |x + 2|

If y is 5 when x is 2.5 and y varies directly with x, the equation is y = kx where k is the constant. k = y/x = 5/2.5 = 2. The equation is y = 2x. When x is 10, y = 2(10) = 20.
