Question

Equation for y and what if equals too

Answer 1

The answer is y = 35x + 20.

In order to find this, start with two ordered pairs. For the purpose of this problem, we'll use (1, 55) and (2, 90). Now we use the slope formula to find the value next to x in the equation.

m(slope) = (y2 - y1)/(x2-x1)

In this equation (x1, y1) is the first ordered pair and (x2, y2) is the second. Plug in to the equation and solve.

m = (90 - 55)/(2 - 1)

m = 35/1

m = 35

Now that we have the slope, plug that into the equation along with either point to find the intercept (the last number).

y = mx + b

55 = 35(1) + b

55 = 35 + b

20 = b

Now that we have the slope and intercept, we can use each to fill in those blanks.

y = 35x + 20

Answer 2

Hey there!

First, we would determine what the first x-axis and y-axis have in difference. We would analyze the following:

For number 1: 55-90= 35 ... 90+35 = 125 ... 125+35=160.

The key number here would be 35.

Therefore, the equation would be the following:

`the \ next \ equation\left \{ {{y=195+35=\bf(230)} \atop {6=2}} \right.`

Answer: y=35x+20
