2X+1/4y=1 solve for Y

y=-8x+4

Step-by-step explanation:

Isolate the Y variable by balencing the equation! Khan acadamy has great videos on how to do this!

Y=4-8x

OR if you want it more specific (slope intercept form)

y= -8x+4

Same thing

Step-by-step explanation:

SO when asked for y you just have to isolate the y

SO we can do that by subtracting 2x on both sides

1/4y=1-2x

Now to get y isloated we can just divide 1/4 on each sides

y=4-8x

THere you go or if you want it in slope intercept form just reverse the signs when switching the positions becuase y=mx+b

y= -8+4

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
