Question

zaid buys a loaf of bread and some broccoli. the graph shows the total cost of function of the number of pounds of broccoli, x. the initial value is 4. it represents the cost of the loaf of bread. the rate of change is 2. it represents the cost of each pound of broccoli. write an equation to represent the total cost, y. y = □ x +? an error has occurred. please enter a number.

Explanation:

Step1: Recall linear equation form

Linear equations follow $y=mx+b$, where $m$ = rate of change, $b$ = initial value.

Step2: Substitute given values

Rate of change $m=2$, initial value $b=4$.
Expression: $y=2x+4$

Answer:

$y = 2x + 4$
