What’s the equation for a line passing through points (-1, 4.5) and (6, 8)?

san4es73 [151]

Answer:

Given points ( -1 , 4.5 ) and ( 6 , 8 )

Step-by-step explanation:

first we should calculate slope 

Slope ( m) 

= ( y2 - y1) / ( x2 - x1) 

= ( 8 - 4.5 ) / ( 6 + 1 )

= 3.5/7

= 0.5

Now the equation of line is given by 

y - y1 = m ( x - x1 )

y - 4.5 = 0.5 ( x + 1 )

( y - 4.5 ) = 0.5 ( x + 1)

y - 4.5 = 0.5x + 0.5

y = 0.5x + 0.5 + 4.5

y = 0.5x + 5

A teacher plans to buy the same number of notebooks and rulers for his classroom. Each notebook costs $2 and each ruler costs $1

Paladinen [302]

Answer:

3x=total amount of money, 3x

Step-by-step explanation:

Because the number of notes books is the same (x and x), you can simply add them.

Basically, the equation is 1x+2x= total cost but you can add 1x and 2x because they have the same variable
