Answer: The required value of b is 4.
Step-by-step explanation: Given that Hank draws a line with a zero slope through the points (-2,4) and (3, b).
We are to find the value of b that could represent Hank's second point.
We know that
the slope of a line passing through the points (p, q) and (r, s) is given by
![m=(s-q)/(r-p).](https://img.qammunity.org/2020/formulas/mathematics/middle-school/hbtw5d1d6qlrjm348v4mmu8irgfwx7uhf0.png)
Since the slope of the line passing through the points (-2, 4) and (3, b) is zero, so we must have
![0=(b-4)/(3-(-2))\\\\\\\Rightarrow 0=(b-4)/(5)\\\\\Rightarrow b-4=0\\\\\Rightarrow b=4.](https://img.qammunity.org/2020/formulas/mathematics/middle-school/3xwhdndwrd4lpzlmj0k0nqkbfktf289c8g.png)
Thus, the required value of b is 4.
