Tanica drew a line of best fit on a scatterplot, as shown below. The equation of the line is y=-1.02x+7.09 Using the line, she predicted that when the value of x is 0.5, the value of y will be approximately 7.6. What was her mistake? A.She drew the line of best fit incorrectly.B.She used the line of best fit to predict y for an incorrect value of x. C.She forgot the minus sign before the first term on the right side of the equation when she predicted y. D.She plugged 0.5 into the equation for y instead of x and actually predicted x instead of y.

30 POINTS !!!!!!!!!!! When dealing with an equation containing two variables, we can put the graph of the equation on the coordinate plane because the number of variables is equal to the number of dimensions that are needed to properly graph the solution. Each axis on a graph represents one variable in the equation being graphed. What would you use to graph the solution to an equation with one variable? What would you use to graph the solution to an equation with three variables? Could you graph an equation containing more than four variables? Explain. If you were given the graph of an equation with two variables on a coordinate plane, what would happen to the graph if all the y-values were increased by 1? What would happen to the graph if all the x-values were increased by 1? What would happen to the graph if all the y-values were multiplied by 2 or by 1/2? Explain
