Answer:

$\huge \boxed{y=14x}}$

Step-by-step explanation:

x=0.5, y=7

x=1, y=14

x=1.5, y=21

x= 2, y=28

Let’s take the first equation.

y = 14x

y = 14(0.5) = 7

When x is 0.5, y is 7.

y = 14(1) = 14

When x is 1, y is 14.

y = 14(1.5) = 21

When x is 1.5, y is 21.

y = 14(2) = 28

When x is 2, y is 28.

Solve the system by substitution. -4.5-2y=-12.5 , 3.35x-y=-0.75

goldenfox [79]

First, we solve for y in the first equation:
$-2y = -12.5 +4.5$
$-2y=-8$
$y= \frac{8}{2}$
$y=4$
Then, we substitute the y value in the other equation and solve for x:
$3.35x-(4)=-0.75$
$3.35x=-0.75+4$
$3.35x=3.25$
$x= \frac{3.25}{3.35}$
$x= \frac{65}{67}$
