Convert the following linear equations in standard form to the slope-intercept form by solving for y in terms of x.

Note:
1) If there is no constant term in the standard form of a linear equation as in

(c) above, b = 0 in the slope-intercept form and the y coordinate of the y intercept (0,

b) is zero. This means that the graph crosses the y axis at the origin. See also Problem 2.13 (g).
2) If there is no x term in the standard form of a linear equation as in (d), the slope m = 0 in the slopeintercept form, y equals a constant, and the graph of the equation is a horizontal line. See Problem 2.13 (h).
