Question

"Given m = -2/5 and b = -7, write the equation of the line containing these points"

Answer 1

Answer:  y = (-2/5)x - 7

This is the same as writing $y = -\frac{2}{5}x-7$

======================================================

Explanation:

Any linear equation is of the form y = mx+b, known as slope-intercept form

m = slope

b = y intercept

We'll replace m with -2/5 and replace b with -7 to get y = (-2/5)x + (-7) which simplifies to y = (-2/5)x - 7
