The glass will contain <u>89.086 milliliters</u> of juice with 7 ice cubes, using the equation of the line of best fit, y = -29.202x + 293.5.
In the question, we are informed that the equation of the line of best fit, for the, scatter plot with x representing the number of ice cubes and y representing the milliliters of juice is given as y = -29.202x + 293.5.
We are asked to tell how many milliliters of juice will be in a glass with 7 ice cubes based on the line of best fit.
To find the milliliters of juice in the glass with 7 ice cubes, we substitute x = 7, in the equation of the line of best fit, to get a value of y, representing the milliliters of juice in the glass.
Thus,
y = -29.202x + 293.5,
or, y = -29.202(7) + 293.5 {Substituting x = 7},
or, y = -204.414 + 293.5,
or, y = 89.086.
Thus, the glass will contain <u>89.086 milliliters</u> of juice with 7 ice cubes, using the equation of the line of best fit, y = -29.202x + 293.5.
