Question

Complete the equation for the linear function whose graph contains the point 
(−1, 2) and has a slope of 0.9.
 
y =   x +

danjs · Answer

same thing.. use the point-slope formula

y - y1 = m*(x-x1)

point(x1,y1)
slope m

danjs · Answer

just put the values into the equation.

twizttiez · Answer

y = 0.9x +  2.9 ah hah!

danjs · Answer

y - 2 = 0.9* ( x - (-1) )

danjs · Answer

y - 2 = 0.9x + 0.9

y = 0.9x + 0.9 + 2

twizttiez · Answer

So i was wrong again D: no!!!

danjs · Answer

using the point slope form, you get

y - 2 = 0.9 *(x + 1)

then distribute the right, and add 2 to both sides

y - 2 = 0.9x + 0.9

y = 0.9x + 2.9
