Write y= - 2/5 x - 3 in standard from using intergers.
a. 2x+5y=-15
b. 2x+y=-3
c. 2x+5y=-3*****
d. x+y=-15
(i believe its C, i need help!)
Yes, you need help
2 x/5 + y = -3
multiply BOTH sides by 5
2 x + 5 y = -15
you are incorrect. As you correctly remembered, the standard form is
Ax + By = C
You multiplied the x and y by 5, but forgot the -3.
A is the correct choice.
To write the equation y = -2/5x - 3 in standard form using integers, we need to rearrange the equation so that the variables (x and y) are on one side and the constant is on the other side. Standard form is typically written as Ax + By = C, where A, B, and C are integers.
Start with the given equation:
y = -2/5x - 3
Multiply both sides of the equation by 5 to eliminate the fraction:
5y = -2x - 15
Now, we want to move all terms to one side to obtain the standard form. Rearranging the equation:
2x + 5y = -15
Comparing this form with the options given, the correct answer is option C: 2x + 5y = -15.
