Hey there.. Lets solve this problem with steps
→ Basic Standard Formula
y = mx + b
→ Step 1 ( taking x to right side or arranging the equation in standard form)
-8y = -4x + 11
→Step 2 ( keeping y at it's own place by dividing both sides by -8)
y =[tex] \frac{-4}{-8} [/tex] x - [tex]\frac{11}{8} [/tex]
y = [tex] \frac{1}{2} [/tex] x - [tex]\frac{11}{8} [/tex]
So, m = slope in standard formula
So, m = [tex] \frac{1}{2} [/tex]
Correct Option is A.
Hope this helped you.. :)
