Answer:
The correct option is;
0.4 represents the height of each block
Step-by-step explanation:
The information given are;
Kirima first builds a firm base of a given height
Kirima is building her wall using uniformly sized bricks
the height of the wall she is building depends on the number of blocks stacked to form the wall
Therefore, variable that depends on other variable, which is the dependent variable, y, is the height of the wall
The independent, which determines the value of the dependent variable is the number of blocks added, x
The gradient of the equation is the height of each block = 0.4
The y-intercept is the starting value, which is the firm base of dimension, 0.6
Therefore, 0.4 represents the height of each block.
