Substitute -3 for x
F(-3)=-5(-3)+12
F(-3)=15+12
F(-3)=27
When the put a value for x in f(x) there telling you the x value
Substitute the x value to get the y value
F(x) can be written as y
Which makes this y=27
which makes the order pair of (-3,27)

Mathematics

$y = \frac{5}{4x} - 2$

4x = 5x = - 8

4x - 5x = - 8

- x = - 8

x = 8

✍️blue line on graph

y = x

✍️Green Line on the graph

$y = \frac{5}{4} \times - 2$

☃️ Hope this helps☃️
Graph the line with the equation Y=5/4x-2
