Answer:
y = 7x - 27
Step-by-step explanation:
assuming you require the equation of the line
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = 7 , then
y = 7x + c ← is the partial equation
to find c substitute (5, 8 ) into the partial equation
8 = 35 + c ⇒ c = 8 - 35 = - 27
y = 7x - 27 ← equation of line
Answer:
1 3/4
Step-by-step explanation:
7/8x4/2
= 7/4
its 7/4 because I simplified 8 and 4 by 4.
The algebraic expressions given by the three students which was derived using the tiles represented in the figure are all correct.
<u>Patti's algebraic expression</u> :
2 - 1 + 2x - 3 could be broken down as follows :
- 2 = two shaded tiles with each having a +1 value
- -1 = white tile which has a - 1 value
- 2x = two shaded tiles labeled x
- -3 = 3 shaded tiles in the negative portion of the rectangle, with each having a - 1 value.
<u>Carla's Expression</u> :
2x + 2 - 4 could be explained thus :
- Carla builds on Patti's expression by summing up the negative values of the tiles.
- 2x + 2 - 1 - 3 = 2x + 2 - 4
<u>Emile's expression</u> :
2x - 2 could be explained thus ;
- Emile simplified the expression further by adding all the constant values to produce a simplified expression
2x + 2 - 1 - 3
2x + 2 - 4
2x - 2
Therefore, all the algebraic representation of the tiles given by the students are all correct.
