How much more would the value of y be in the table than its value on the graph, when x = 11? (1 po

Answer 1

Answer: To determine the equation of line, we need two points that is passing through the line. Thus, the value of y is 495 when x is equal to 11.

A line passing through the ordered pairs 2, 90 and 4, 180 and 6, 270 and 8, 360.

Thus, the points that is lie on the line is (2,90) and (4,180).

The equation of line passing through the two points (x1,y1) and (x2,y2) can be formulated as:

There, substitute the values and solve it further.

Thus, substitute the value of x=11 in above equation.

Therefore, when x=11, the value of y is 495.
