Hello, thank you for taking the time to post your question!
For the equation 2x−4y+10=0, you need to rearrange it to the slope-intercept form, which is y=mx+b.
Solving that algebraically for the value of “y” yields:
2x−4y+10=0
−4y=−2x−10
y=-2x/4 + -10/-4
y=1/2x + 5/2
I hope that helps you get moving in a better direction on this type of question! Feel free to reach out if you have any additional questions beyond that :)
