Answer:
The right answer is : f(-4)=5
First you would need to convert the equation to match the y = mx + b format.
Subtract 2x from both sides to get -y = -2x + 3
Then, divide -1 (because that's the coefficient to -y, on all values, turning to equation into
y = 2x - 3 (negative and negative makes a positive that's why the 2 value is now positive) in order to make the y value positive.
Our y intercept is -3 so start your graphing line on the -3 value on the x axis.
Our slope is 2/1 which means to go up 2 point and right 1 point, since it's a positive slope.
You can mark every point in order to get a more accurate line and just connect the dots from there. Be sure to use a ruler or some sort of straightedge for a better line.

Answer:
7,366,327.50 pascals
Step-by-step explanation:
we know that
1 atm= 101,325 pascals
we have
72.7 am
Convert to pascals
72.7 atm=72.7*101,325=7,366,327.50 pascals
155.2 + 0.4 = 155.6
155.2 - 0.4 = 154.8
so it ranges from : 154.8 to 155.6
