Answer
(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 $v_0$
