Answer: y = x

Step-by-step explanation: Since the input for the first equation is 2, the x is 2. Use this for the other equation. Now, your ordered pairs are (2,2) and (1,1). If you find Δy/Δx, you get m = 1. Plug in m to the equation. Next, put any ordered pair in there. For example: 1 = 1(1) + b. If you solve for be the answer is..... 0. Nice. Your final equation is y = 1x + 0, or y = x.

A line passes through the points (2,21) and (8,27). Write a linear function rule in terms of x and y for
tatiyna
We have two points so we can find the gradient using y1-y2/x1-x2
gradient = 21-27/2-8
= 1
we know the form for any linear equation is y = mx + c
we have m and a point so we can substitute in point (2,21) to find c
21 = 1 x 2 + c
c = 19
therefore, the equation is y = x + 19

3/4- 30= -29.25 and that was only 20% of the box that was dropped out of the box. -29.25 of 20% equals -5.85. 3/4 of 20% equals 0.15 subtract the 2 decimals and you will get -5.7
