Answer:
y = 4/5x + 1
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
y = 4/5x + 1
The change in grandpa Ernie's height each year is equal to 0.6cm.
As given in the question,
Number of years for which grandpa's height is shrinking = 4 years
The total decrease in height after four years is equal to 2.4cm.
Let x represents the decrease in height each year
The required equation to calculate decrease in height each year is given by:
4x = 2.4
⇒ x= 2.4 /4
⇒x = 0.6cm
Therefore, the change in grandpa Ernie's height each year is equal to 0.6cm.
The complete question is :
Grandpa Ernie is shrinking over the past four years his height decreased by a total of 2.4 cm it decrease by the same amount each year what was the change in grandpa Ernie’s height each year.

Y = 1/3x + 2
Explanation- find the slope. By looking at the first point, you go up 1 and over 3, making slope 1/3. Or you can find the slope with the equation:
m = y2-y1
———
x2-x1
The y intercept is on the y axis at 2.
So, The equation is y = 1/3x + 2
