linear equations in two variables

The graph of linear equation x+2y = 2, cuts the y-axis at

• (2,0)

• (0,2)

• (0,1)

• (1,1)

If x-5 =√3y in the form of ax+by+c=0 then b=

• 5

• 1

• √3

• -√3

Variables in ax+by+c=0 are

• x

• y

• x,y

• a,b,c

Write an equation in Standard Form.
A store sells t-shirts for $12 each and sweatshirts for $15 each. You plan to spend $120 on t-shirts and sweatshirts.

• 2x + 5y = 120
• 12x + 15y = 120
• 12 + 15y = 2x
• 12x + 15 = 120

In linear equation 'ax+by = c' a,b and c are considered as

• zero

• real numbers

• constants

• variable

x + 20 = 100

• x = 80

• x = -5

• x = 20

• x = -80

• y - 3 = -5(x + 2)
• -7x + 2y = 9
• 3x + 2 = y

Variables in ax+by+c=0 are

• x

• y

• x,y

• a,b,c

If a system of equations has no solution, what does the graph look like?
