I think the correct answer is D
slope intercept form is y = mx+ b
lets get the equation in that form
8y = 2x+4
divide each side by 8
8y/8 = 2x/8 + 4/8
y = 1/4x + 1/2
the slope or m is 1/4
Choice C
Answer:
y-4=-2(x-1)

Answer:
There are 30 students in the class
Step-by-step explanation:
we can write a ratio as:
8:10 as 24:x
Writing this as an equation gives:
8
10
=
24
x
We can now solve for
x
while keeping the equation balanced:
