a.) $\frac{2}{3}$ b.) 6 c.) y=$\frac{2}{3}$x+6

Work Step by Step

a.) m=$\frac{y_2-y_1}{x_2-x_1}$ m=$\frac{6-4}{0-(-3)}$ m=$\frac{2}{3}$ b.) Any line will cross the y-axis when its x value is equal to zero. According to the table when x is zero, y is 6. Therefore, the y-intercept is b=6. c.) y=mx+b y=$\frac{2}{3}$x+6
