What is the slope of the line with the coordinates (0,0) and (-4,7).
Citrus2011 [14]

Answer:

Slope = -7/4

Step-by-step explanation:

Let's find the slope between your two points.

(0,0) ; (−4,7)

(x1,y1) = (0,0)

(x2,y2) = (−4,7)

Use the slope formula:

m = y2−y1 / x2−x1

= 7−0/−4−0

=7/−4

= −7/4

Answer:

m= −7/4

Hope this helps!!
