25/53 would be the simplest answer
The Solution:
Given:

Required:
To write the given equation in the form below:

Clearly, the given equation is already in the required form.
The parameters are:
*ahem* the actual Awnser is 79.25 because 63.4 divided by 72 is 0.8805 and if you multiply that by 90 you get 79.25
Answer:
-25
Step-by-step explanation:
2a² - 5a + 4, for f(-3)
2(-3)² -5(-3)+4
2*(-27)+15+4
-54+19
= -25
Find points and find the slope from the points. Then plug the points into the equation along with the slope and then you can solve for b
