Question

No one helped me with the last question but i got it can someone help me with this

Answer 1

y = 2x

Step-by-step explanation:

The linear functions are given by:

y = mx+b

To find the slope, we have to find the change in x and y

The change in x is:

$-14-(42) =-14+42 =28\\14+14= 28$

The change in y is:

$-28-(-84) = -28+84 = 56\\28-(-28) = 28+28 = 56$

The slope is:

$Slope = \frac{change\ in\ y}{Change\ in\ x}\\=\frac{56}{28}\\= 2$

Putting slope in equation of linear function

$y =2x+b$

To find the value of b, we will put any pair of input and output in the slope-intercept form

So, putting (14,28)

$28 = 2(14) + b\\28 = 28+b\\b = 28-28\\b = 0$

Hence,

the linear equation for function is:

y = 2x
