Line AB contains points A (8, −4) and B (1, −5). The slope of line AB is

Question

anonymous · Answer

M is the slope:

$$m = \frac{ (y-y_0) }{(x-x_0) }$$

anonymous · Answer

Your points are in the form (x, y)

anonymous · Answer

(-5 -( -4) / (1 - 8) would i start like this?

anonymous · Answer

Yes

anonymous · Answer

ok... -1 / -7 ?

anonymous · Answer

would the answer be - 1/ 7 ?

anonymous · Answer

Correct but a negative divided by a negative creates a positive

anonymous · Answer

So it would be positive 1 over 7 not negative 1 over 7

anonymous · Answer

Line AB contains points A (8, −4) and B (1, −5). The slope of line AB is

A) −7

 B) negative 1 over 7

 C) 1 over 7

D)  7
these are my choices

anonymous · Answer

If it does not indicate a negative sign then you assume that the value is positive so which would be a positive 1 over 7?

anonymous · Answer

so c?

anonymous · Answer

Correct!

anonymous · Answer

yayy! thankyou !!!

anonymous · Answer

Not a problem!

anonymous · Answer

could you help me with another one i don't know how to get started?

anonymous · Answer

The equation of line AB is y = 5x + 1. Write an equation of a line parallel to line AB in slope-intercept form that contains point (4, 5).
