How do you write a linear function? For those 2 problems?? (attached)

(9) The linear function is

(10) The linear function is

Explanation:

(9) The coordinates from the graph are (-6,1), (-3,2), (0,3) and (3,4)

Linear function:

The linear function can be determined using the formula,

The y - intercept of the line is the value of y when x = 0.

Thus, from the graph, we have,

Let us substitute the points (-6,1), (-3,2) in the slope formula,

Thus, the slope is

Substituting the value and in the formula , we get,

Thus, the linear function of the equation is

(10) Linear function:

The linear function can be determined using the formula,

The y - intercept of the line is the value of y when x = 0.

Thus, from the graph, we have,

Let us substitute the points (-2,7) and (2,-7) in the slope formula,

Thus, the slope is

Substituting the values and in the formula, we get,

Thus, the linear function of the equation is

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
