(a) The slope of this line is $a$ (b) The vertical axis intercept is $v_0$

#### Work Step by Step

(a) In general, a straight line has this form: $y = mx + b$ $m$ is the slope $b$ is the vertical axis intercept The equation given in the question is: $at = v-v_0$ We can rewrite the equation: $v = at+v_0$ The slope of this line is $a$. (b) The vertical axis intercept is $v_0$
