Line passes through the points (3 comma 19 )and (7 comma 23 ). write a linear function rule in terms of x and y for this line.

Step-by-step explanation:

Two given points are (3,19)  and (7,23)

f(x)=mx+b

slope is m  and b is the y intercept

slope m= 1  (3,19) is (x1,y1)

Add 19 on both sides

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
