Find the slope of the line. (If an answer is undefined, enter UNDEFINED.)
−4x + 5y = 9
I did:
−4x + 5y = 9
5y = 4x+9
y=(4/5)x +(9/5)
when I Put (4/5)x +(9/5) on my online assignment, it said can not understand or grade it,
then I put 0.8x + 1.8 and it said incorrect answer.
what other answer do I put?
if they want the slope, just give them the slope, not the equation of the line!
To find the slope of a line, you need to rewrite the equation in the form of y = mx + b, where m represents the slope. Let's go through the steps to find the slope of the given equation:
-4x + 5y = 9
1. Begin by isolating y on one side of the equation:
5y = 4x + 9
2. Divide every term in the equation by 5 to solve for y:
y = (4/5)x + 9/5
The slope of the line is the coefficient of x in the equation, which is 4/5. However, it seems like the online assignment expects the slope to be expressed in decimal form. To convert 4/5 to a decimal, divide the numerator (4) by the denominator (5):
4 ÷ 5 = 0.8
Therefore, the slope of the line is 0.8. If the online assignment does not accept fractions or decimals, you may need to enter the slope as a whole number. Since 0.8 can be written as 4/5, you can also try entering the slope as 4/5 or 4.
