1. Determine whether the given point lies on the graph of the equation. Note: You are not asked to draw the graph.

(a - 1, a + 1); y = x + 2

2. Graph the equations after finding the x- and y-intercepts.

a. 3x + 4y = 12

b. x = 2y - 4

3. The figure shows the graph of an equation. Find the x- and y- intercepts of the graph. If an intercept involves a radical, give both the radical form o f the answer and a calculator approximation rounded to two decimal places. (Check to see that your answer is consistent with the given figure uploaded)).
