PRE-CALCULUS HELP: Can somebody write this equation in slope-intercept form?

Question

3x + 4y = 7

Well, I already know the answer but I don't know how you get it

- If you could just give me a brief explanation if anybody knows how to do this

Answer 1

I&#039;m sorry, but how is that pre calculus? i had that equation last year in algebra 1

Answer 2

So you know that slope intercept for is y=mx+b (or y=ax+b)

Thus, you simply isolate y:

3x + 4y = 7

7-3x=4y

(7/4)-(3/4)x=y

Making it: y=-3/4x+7/4

Hope that cleared it up for you!

Answer 3

slope intersept form is y=m(x)+b.

the m(x) is the slope of the equation.

b is your y-intersept (where the line meets the vertical y axis)

so, you want to get y by its self on one side of the = sign.

to do that you would subtract 3x from both sides, to get 4y = -3x + 7

then you would divide by 4 on each side, to get 4y = -3x + 7

                                                                     /4      /4    /4

now since your slope is rise over run, a fraction is good. don&#039;t try to turn it into a decimal.

so you get y = -3/4 + 1 and 3/4.

any other qu.s e-mail me!

Answer 4

3x + 4y = 7

subtract -3x from both sides

4y= -3x +7

div by 4 both sides

y = -3x/4 +7/4

Answer 5

You move 3x to the other side first,

4y = -3x + 7

Divide both sides by 4,

y = -(3/4)x + (7/4)

Answer 6

Slope intercept form has the basic form of y=mx + b, where m is the slope and b is the y-intercept (the point on the y axis that the line crosses). To get to slope intercept form, you must solve the equation for y. First, subtract 3x from both sides so you have 4y = -3x + 7. Next, divide by 4 to get y by itself. This gives you y= -3/4 x + 7/4. This means that the slope is -(3/4) and the y-intercept is (7/4).  

Answer 7

Slope-intercept form means &quot;get the equation to look like y=mx+b&quot;

You want to get y all alone on the left side. Start by subtracting 3x from both sides:

4y=-3x+7

Now divide each term by 4 to get y all alone.

y=(-3/4)x+(7/4)
