Find the equation in standard form which passes through (–1, 4) and (0, 9)

anonymous · Answer

$$m=\frac{ y2-y1 }{ x2-x1 }$$
$$y - y1 = m*(x - x1)$$

anonymous · Answer

The slope is 5 right?

anonymous · Answer

y-9 =5(x-0)

anonymous · Answer

yes, but still not done yet
solve for y

y = mx + b

anonymous · Answer

I don't really know how to use that equation/: i never learned it

anonymous · Answer

y-9 =5(x-0)
distribute the 5 what do you get?

anonymous · Answer

y-9 = 5x - 0 ?

anonymous · Answer

yes
now move the 9 to the other side what do you get?

anonymous · Answer

then subtract 5x from both sides?

anonymous · Answer

no you need to add 9 to both sides

anonymous · Answer

y-9 = 5x 
+9     +9
y = 5x + 9

anonymous · Answer

wait but I need to put it in standard form

anonymous · Answer

y = 5x + 9
ok subtract the 5x and you will be good

anonymous · Answer

Standard Form: Ax + By = C

slope-intercept form: y = m x + b

anonymous · Answer

yeah i know but I think I got it now I figured it out thank you for helping me understand tho c:
