Answer:

The graph in the attached figure

Step-by-step explanation:

we have the ordered pairs

(-4,9),(-1,3),(0,1),(2,-3)

Using a graphing tool

Plot the given ordered pairs in the coordinate plane

Remember that

In a ordered pair (x,y), the first coordinate is the location of the point in the x-axis and the second coordinate is the location of the point in the y-axis

see the attached figure

The graph represent a line

Find the equation of the line

Find the slope

take two points

$(0,1),(2,-3)\\m=(-3-1)/(2-0)=-2$

The equation of the line in slope intercept form is equal to

$y=mx+b$

we have

$m=-2\\b=1$

substitute

$y=-2x+1$

8 + 4f = 3f solve for f

Answer:

$f=-8$

Step-by-step explanation:

$8+4f=3f$

$8+4f-4f=3f-4f$ (Subtract $4f$ from both sides of the equation to isolate $f$ )

$8=-f$ (Simplify)

$-f=8$ (Symmetric Property of Equality)

$\frac{-f}{-1} =\frac{8}{-1}$ (Divide both sides of the equation by $-1$ to get rid of $f$ 's coefficient; remember that $-f=-1*f$ , so $-f$ has a coefficient of $-1$ )
