Answer:
b
Step-by-step explanation:
first you have to turn each equation into standard form
so...
a) 3y - 12 = 4x
add 12 to both sides
3y = 4x + 12
divide everything by 3
y = 4/3x + 4
b) 4y - 12 = 3x
add 12 to both sides
4y = 3x + 12
divide everything by 4
y = 3/4x + 3
c) 3y + 12 = 4x
subtract 4 from both sides
3y = 4x - 12
divide everything by 3
y = 4/3x - 4
d) 4y + 12 = 3x
subtract 12 from both sides
4y = 3x - 12
divide everything by 4
y = 3/4x - 3
then look at the graph
find the y intercept first (which is the last number in the equations)
so...
a) 4
b) 3
c) -4
d) -3
the line meets a 3 on the y axis so the y intercept is 3 so you can already tell the answer is b.
but to check yourself you would see that the points is up 3 over 4 so 3/4 is the slope so thats the number infront of x.
