Find the value of $y$ when $x=1$ in the equation $y=-3x+2.5$ .

STEP 1

Assumptions
1. We have the equation $y = -3x + 2.5$ .
2. We are asked to find the value of $y$ when $x$ is 1.

STEP 2

To find the value of $y$ when $x$ is 1, we substitute $x = 1$ into the equation.
$y = -3(1) + 2.5$

STEP 3

Now, we perform the multiplication and addition to find the value of $y$ .
$y = -3 \cdot 1 + 2.5$

STEP 4

Calculate the multiplication.
$y = -3 + 2.5$

STEP 5

Now, calculate the sum.
$y = -0.5$
The value of $y$ that makes the equation true when $x$ is 1 is $-0.5$ .
