Through (-1,2), slope = 2 in standard form

2x-y = -4

Step-by-step explanation:

We can use the point slope form of a line to write the equation and then convert it to standard form

y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point

y-2 =2(x--1)

y-2 =2(x+1)

y-2 =2x+2

The standard form is Ax +By =C

Subtract 2x from each side

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

-2x+y-2 =2

Add 2 to each side

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

-2x+y=4

The x term should be positive

Multiply by -1

2x-y = -4

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
