Question

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

Answer 1

Any ideas?

Answer 2

slope=y difference/x difference

Answer 3

$$\Huge slope=\frac{\delta{x}}{\delta{y}}=\frac{y_2-y_1}{x_2-x_1}$$

Answer 4

slope can be found using the formula

m= (Y2-Y1)/(X2-X1)
m is the slope of the line
the order of which is 1 and 2 does not matter :P

for (4,-2) and (-5,4) that would be

m=(4-(-2))/(-5)-4) = (4+2)/(-5-4) = 6/-9 = -2/3

the slope of the line is {-2/3}

hope it helped
good luck :P
