![y = - \frac{1}{2} x+ 22](https://tex.z-dn.net/?f=y%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20%20x%2B%2022)
Step-by-step explanation:
making a table of values. find the slope which is change in y divided by change in x. plug in one of the x values and the slope to the equation y = mx + b where m is the slope and x is one of the x points. solve by multiplying the x value you chose to slope then add that to the y value of the x you chose which will be the y int which is 22
A number that can be expressed as a fraction with integer values in the numerator/denominator.
Answer:
x = 2 or 1/4
Step-by-step explanation:
by solving it we get ;

![(4x - 1)(x - 2)](https://tex.z-dn.net/?f=%284x%20-%201%29%28x%20-%202%29)
so,
