I need the Slope-intercept form, Slope, and Y-intercept for each of these problems...
1. 3x-5y=10
2. y-3=2(x-4)
3. y+5=-3(x-(-1))
4. 2x-3y=6
5. y-4=0
6. y+1=1/2(x-(-3))

Wouldn't this have gone better in Mathematics rather than Geography? Plus, this seems more like algebra rather than geometry. A minor distinction perhaps.

Slope intersept form is simply y=mx+b, where m is the slope, and b is the y-intercept. Merely solve for Y in terms of X and you'll have the answer. For example, if the question was 2y-4x=2, then you would subtract 2x from both sides of the equasion, giving you 2y=4x+2, then divide by 2 to get y all by itself, giving you y=2x+1. The 2 in front of the x is the slope, and the 1 is the y-intercept (and no, I won't give you the answers, that defeats the purpose.) In the case of question 4, however, imagine that there is an imaginary 0x, with 0 being the slope. By the way, symplify all the equasions so you have a number times x, a number times Y, and another number, before you start the problem.

1. y=0 when x=+3.33333333 and x=0 when y=-2
2. y=0 when x=+2.5 and x=0 when y=-5
3. y=0 when x=-8/3 and x=0 when y=+8
4. y=0 when x=-3 and x=0 when y=+1
5. y is a line and is =+4 and there is no x intercept
6. y=0 when x=-1 and x=0 when y=+.5

1. y=3/5x - 2
2. y=2x - 5
3. y=3x + 8
4. y=2/3x - 2
5. y=4
6. y=1/2x = 2.5
And you posted this under geography, not geometry, there's a difference.

truthfully, the in uncomplicated words ingredient that i visit discover in immediately ahead with sacred geometry and alchemy is they both manage sorts of spirituality. Sacred geometry deals with using geometric kinds and shapes in the layout and structure of churches, temples, mosques or everywhere of non secular amassing. those certain shapes recommend particular issues, depending on the religion or perception gadget. as an get at the same time, the pentagram in Christianity refers back to the 5 senses. In Catholicism, it would want to each now and then verify with the devil, or the Evil One. Alchemy deals with the approach of turning metals into gold, making use of chemical substances and technological information. inspite of the undeniable fact that, Alchemy is likewise a perception in looking the perfect information by skill of chemistry. for this reason, alchemy is a spirituality all its personal. All in all, the in uncomplicated words ingredient that i visit work out in immediately ahead between both is they both manage a type, or sorts, of spirituality.

First off, this section is Geography, not Geometry. Second off, these questions are Algebra, not Geometry.
