(1 pt.) We use the equation "c1 * x + c2 * y = b" to represent a dividing line. Suppose that c1 gt; 0 and c2 gt; 0.

(1 pt.) We use the equation "c1 * x + c2 * y = b" to represent a dividing line. Suppose that c1 > 0 and c2 > 0. If you were to rewrite the equation as "y = intercept + slope*x", then what can you say about the sign of the slope? a. Slope must be positive b. Slope must be negative c. The sign of the slope depends on the sign of b d. The sign of the slope depends on the magnitude of c1
