Question

x | y = 1,25x - 3/4
-1 | -2
0 |
1 |
2 |
3 |

Explanation:

First, convert the values to fractions for consistency: $1.25 = \frac{5}{4}$, so the function is $y = \frac{5}{4}x - \frac{3}{4}$.

Step1: Substitute $x=0$

$y = \frac{5}{4}(0) - \frac{3}{4} = -\frac{3}{4} = -0.75$

Step2: Substitute $x=1$

$y = \frac{5}{4}(1) - \frac{3}{4} = \frac{5-3}{4} = \frac{2}{4} = 0.5$

Step3: Substitute $x=2$

$y = \frac{5}{4}(2) - \frac{3}{4} = \frac{10-3}{4} = \frac{7}{4} = 1.75$

Step4: Substitute $x=3$

$y = \frac{5}{4}(3) - \frac{3}{4} = \frac{15-3}{4} = \frac{12}{4} = 3$

Answer:

$x$	$y$
0	$-0.75$ or $-\frac{3}{4}$
1	$0.5$ or $\frac{1}{2}$
2	$1.75$ or $\frac{7}{4}$
3	$3$
