What is the equation of the line passing through the points (–2, 2) and (3, –1)?

anonymous · Answer

first find the slope between these two points.

anonymous · Answer

slope is 3

anonymous · Answer

no!
slope = y2 - y1 / x2 - x1
y2 - y1 = -1 - 2 = -3
x2 - x1 = 3 +2 = 5
so what is slope?

anonymous · Answer

how did gou find 3?

anonymous · Answer

4

anonymous · Answer

NO! i said you try again! -3 / 5 is 4?!!!! :| :|

anonymous · Answer

do u know slope formula?

anonymous · Answer

noo

anonymous · Answer

slope = (y2-y1)/(x2-x1)

anonymous · Answer

i just told you.if you don't know slope formula then how do you find these answers? :D

anonymous · Answer

yes slope is:
$$Slope = \frac{ y _{2} - y _{1} }{ x _{2} - x _{1} } $$

anonymous · Answer

now find slope.

anonymous · Answer

Find the slope (m), then just insert the numbers to this formula to find the equation: $$y-y_{1}=m(x-x_{1})$$

anonymous · Answer

@Dequavia123 , u still need help?

anonymous · Answer

besides this,u can find y-intercept and then put them in this equation:
y = mx + d
m -> slope
d -> y-intercept
