Well for problems like this you need to look at what is plotted. And you need to look at the y intercept which is the vertical line and the x intercept which is the horizontal line. I think the answer is B because of what is plotted. I am not 100% sure but I think it is. Let me try to look into it more but what is this for? Hw assignment?

Determine the pattern rule for the table and write it as an equation.

fomenos

Answer:

The rule is: y = -10x+85

Step-by-step explanation:

The rule is given by:

$y = mx+b$

Here m is the gradient and b is the y-intercept.

We have to take two pairs of input-output to find the rule

Let the two pairs be:

(x1,y1) = (1,75)

(x2,y2) = (2,65)

Slope is found using the formula:

$m = \frac{y_2-y_1}{x_2-x_1}$

Putting the values

$m = \frac{65-75}{2-1}\\m = -10$

Putting the value of slope

$y = -10x+b$

Putting a pair of input-output in the equation (1,75)

$75 = -10(1) +b\\75 = -10+b\\b = 75+10\\b = 85$

Putting the value of b

$y = -10x+85$

Hence,

The rule is: y = -10x+85
