write an equation of the line in standard form with integer coefficients.
11) 5x - y + 6 = 0
12) y + 1 = 2(x - 3)

see explanation

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

11

5x - y + 6 = 0 ( subtract 6 from both sides )

5x - y = - 6 ← in standard form

12

y + 1 = 2(x - 3) ← distribute parenthesis

y + 1 = 2x - 6 ( subtract y from both sides )

1 = 2x - y - 6 ( add 6 to both sides )

7 = 2x - y, thus

2x - y = 7 ← in standard form

see explanation

Step-by-step explanation:

The equation of a line in standard form is

11

5x - y + 6 = 0 ( subtract 6 from both sides )

7 = 2x - y, thus

2x - y = 7 ← in standard form

2x - y = 7

Step-by-step explanation:

2x - y = 7

Step-by-step explanation:

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.

make sure you have version 2.50

try looking in the very back of the book : )
