i need help with algebra?

it says write each equation in slope/y-intercept for;then identify the slope and y-intercept.

y=2x-3

y=7-2x

y=x/2-1

y=3x/2+4

y=x

y= 1/2-5x/2

mmmk…here we go slope intercept form is (y=mx+b, the m is a # and the slope, the b is a # and the y intercept )

1. is in slope intercept form so

slope=2 Y intercept= -3

2. is not in slope intercept form, so you have to switch the -2x and the 7,

slope=-2 y intercept= 7

3. it is in slope intercept form. so,

slope= 1/2 (the one on top came from the # of x’s there is) Yintercept=-1

4.it is in slope intercept form, so

slope= 3/2 y intercept=4

5.this looks wierd, but it is in slope intercept form,so

slope=1 (the # of x’s) and the y intercept=0 (because thier is no # )

6. This is not in intercept form, so switch the -5x/2 and the 1/2 like in #2 so,

slope=-5/2 (make sure you include the minus, when you move the -5x/2 it moves as a whole, with the minus!)

Y intercept= 1/2

Well all of these equations r in slope/y-intercept form n all u gotta do is figure out the slope and y intercept and thats how u do it:

For example:

y = 3x + 6

So any number infront of ‘x’ is your slope and in this case it is 3, so thas ur slope while your y-intercept is the constant ( or any number that’s written separate without a variable(x, y, z etc) attached to it). In this case its obviously 6. I am not gonna tell u all the answers since i think it explained well enough, but for ur fifth question i.e y= x, the slope is 1 and since u dont see any separate number or constant in the equation, the y-intercept is 0.

Hint: Always put the ” x terms” first in the equation like for instance if u have y = 2 + 6x, so put it like y = 6x + 2 (makes life easier and problem easy to solve and its the same thing, but dont forget to put the correct signs.)

The slope is the number infront of x

eg: y=2x-3, Our slope would be 2

y-intercept is the number without the x

eg: y=2x-3, Our y-intercept would be -3

1. =yx4

2. =4y7

3. =y9x0

4. =4.5

5. =y1x3

those are ya anwsers hope it helped
