A line passes through the point (-8,4) and has a slope of -5/2

Answer 1

In this question, I see you are listing a point and a slope. Are you looking for the equation of the line?

If so, use the point - slope form of a line: y = m x + b

with the the slope m being equal to -5/2

If you substitute the x coordinate of -8 and the y coordinate of 4 , you can solve for b (the y intercept):

4 = -5/2 * (-8) + b

4 = 20 + b

Subtract 20 from both sides:

= 16)4-20 = 20 + b -20

-16 = b

The equation would then be: y = -5/2 x -16

(Recall that a negative number times a negative number gives a positive product for a result

(-5/2 * (-8)) = 16

Let me now if you were looking for something other than the equation of the line.
