30 ~ 45
40 ~ 60

She can work 60 in an hour and a half. We find this by figuring out how many minutes are in an hour and a half (there are 90 minutes), dividing that number by 15 (which equals 6), and multiplying that number by 10 (which equals 60). 60 problems is the answer.

Write the equation of the line that passes througlī the points (-2, 6)

elena-s [515]

Answer:

Horizontal line (0 slope)

Step-by-step explanation:

The equation is $\frac{y2-y1}{x2-x1}$ , so you'd just insert what you know.

It would look like this: $\frac{6-6}{4-(-2)}$ .

We would solve. 6-6=0, while 4-(-2)=6.

So, we have 0/6, which gives you 0, and it would be a horizontal line, since a horizontal line is portrayed by 0 slope.
