Question

use the graph to estimate the value of y when x = 2.5
​

Answer 1

Answer:

7 ish

Step-by-step explanation:

if you look at where 2.5 would be on the X axis (in-between 2 and 3) and you look at the corresponding Y point, its somewhere near where 7 would be.

Answer 2

Answer

The estimated value of $y$ using graph is $6.5$ when $x=2.5$ for the equation $y=3x-1$.

Linear Equation

The linear equation is defined as an equation that has the highest power as one.

We will first plot the graph and then, evaluate the value of the function at the determined point.

How to evaluate the value of the function at a point using a graph?

We can see from the graph that the approximate value of $y$ is about $6.5$ when $x=2.5$.

We can also verify our answer by putting the value of $x$ in the given equation.

$y=3(2.5)-1\\y=7.5-1\\y=6.5$

Thus, the estimated value of $y$ is $6.5$ when $x=2.5$.
