What is the slope and y-intercept of this equation?
2x+4y=14
Answers
Answer 1
Answer:
Equations don't have slopes or y-intercepts, but their graphs might.
Let's solve this equation for 'y', and see whether its graph has them.
2x + 4y = 14
Subtract 2x from each side: 4y = -2x + 14
Divide each side by 4 : y = -1/2x + 7/2 .
In this form, we can look at the equation, and see immediately that
if we were to draw its graph, then the graph would be a straight line
with slope= -1/2 and y-intercept= 7/2 .

Ok, so to do this you need to set up a proportion. They give you miles per gallon. So your proportion looks like this: m/g=m/g. Now subsitute in what they give you. The proportion looks like this: 349.2. X -------- = ---- 38.8 14.6 Your answer should be 131.4 miles Hope this helps!

4x + 3y = 0
2x + y = -2
take 2x and subtract to the side with -2
it'll look like this: y = -2x - 2
plug that equation in where the y is in the other equation.
it'll look like this: 4x + 3(-2x - 2)=0
which you multiply 3 and the -2x and the -2
which the equation would be: 4x - 6x - 6=0
put together like terms: -2x - 6=0
add the 6 to the side with the zero: -2x = 6
divide both sides by -2 which x= -3
to get y you plug in the answer for x (-3)
2(-3)+y= -2
so it'd then be -6 + y = -2
add the -6 to the side with -2
y= -2 +6
y= 4
so your complete answer is ( -3, 4)
