Question

What is the slope of the line passing through the points (2, 5) and (0, -4)

___/___

Answer 1

@amistre64

Answer 2

one option is to play with the slope formula

Answer 3

Equation of a line:
y = mx + b
m = slope
\[m = \frac{ y_2 - y_1 }{ x_2 - x_1 }\]

Answer 4

i don't understand :/

Answer 5

how do you define a slope?

Answer 6

i know the formula for slope but i don't really know how to do it :/

Answer 7

ok, you know the formula ... then we simply have to label the parts

Answer 8

(2 , 5) and (0, -4)
x1 y1 x2 y2

put them in the formula, the rest is adding

Answer 9

so if (mx) would be 2,5? and (0,-4) is b? or something like that

Answer 10

cause the formula is mx+b

Answer 11

the slope formula is not mx + b

Answer 12

y1-y2
slope = --------
x1-x2

as previously pointed out

Answer 13

given 2 points, and label them

(2 , 5) and (0, -4)
x1 y1 x2 y2

fill in the slope formula

Answer 14

x= 2,5
0,-4?
