Final answer:
To find the right equation representing the growth of a tile pattern, one needs specific details about the pattern. All options given are in the correct form y = mx + b, but the right one depends on the initial value and growth rate of the pattern.
Step-by-step explanation:
The question asks for an equation that models the growth of a tile pattern, which can be represented with a linear equation of the form y = mx + b, where m represents the slope (rate of change) and b represents the y-intercept (the value of y when x is 0). The four options provided are all in the linear equation form. To determine the correct equation for growth, one would need specific information about the tile pattern's initial value and the rate at which it grows. Without this information, we cannot confirm which equation is correct. However, Practice Test 4 Solutions suggests that for a line equation such as y = 9 + 3x, to construct a table or a graph, one can plug in a series of different values for x and calculate the corresponding y value. Points can be plotted and a line drawn through them to visually represent the equation and its growth pattern.
