Answer:
Step-by-step explanation:
The rate of change is a measure of the slope
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (29, 9) and (x₂, y₂ ) = (33, 10)
m = =
← rate of change

Answer:
The equation of the line is y = (-1/2)x + 5
Step-by-step explanation:
First of all, have to find gradient using the formula above :
(2,4) & (14,-2)
m = (-2-4) / (14-2)
= -6 / 12
= -1/2
Second, using y = mx + b as b is a constant and is a y-intercept. Using any of these 2 coordinates to find the value of b with given gradient :
y = mx + b
Let y=4 & x=2
4 = (-1/2)(2) + b
b = 4 + 1
= 5
Lastly, put the value of gradient and y-intercept into the equation :
y = mx + b
Let m=-1/2 & b=5
y = (-1/2)x + 5
