J(x)=67x
so if it was j(1)=67(1)
so j(15)=67 x 15= 1005

What is the slope of the line that passes through the points (1, -7) and

ser-zykov [4K]

Answer:

Step-by-step explanation:

To find the slope of a line, you have to use the slope formula: $\frac{y_{2}-y_{1} }{x_{2} -x_{1} }$

So, plug in the numbers: $\frac{-7-(-7)}{-2-1}$

Simplifying it becomes: $\frac{-7+7}{-2+-1}$ . It then becomes $\frac{0}{-3}$ .

Finally, dividing 0 by -3 gets you 0.
