Question

Write the equation in slope-intercept form. What are the slope and y-intercept?

-11x + 9y = -12

Answer 1

-11x+ 9y = -12
add 11x to both sides
+11x +11x
__________________
9y = 11x -12
divide 9 to both sides
y = \[\frac{ 11 }{ 9 }x -\frac{ 12 }{ 9 }\]

You can simplify \[-\frac{ 12 }{ 9}\]to \[-\frac{ 4 }{ 3}\]

so y= \[\frac{ 11 }{ 9 } x - \frac{ 4 }{ 3}\]

and the slope in the y=mx+b form is the "m" part , Rise over run, the y -intercept is the "b"

Answer 2

What is the slope of the line that passes through the given points?

(6, 2) and (7, 4)

Answer 3

wait but thats not a answer

Answer 4

nvm!! sorry thankssss

Answer 5

Really? Hmm.. well the slope would be 11/9x and Y-intercept is -4/3 , or I must be wrong somewhere.

and use the slope formula on (6,2) and (7,4)
x\[x _{1} = 6 , x _{2} = 2 , y _{1} = 7 , y _{2} =4\]
m = \[y _{2} - y _{1} / x _{2} - x _{1}\]

Answer 6

Just plug it in and you'll find the slope
