1. y=x+9 2.y=3x+7 3.y=4x+8 4.y=7x
5.y-*=3(x=1) 6.y+2=2(x-1) 7.y-1=4(x+3) 8.y-3=1(x+7)
When answering each equation, please refer to which one EXP: 6.Y+2=2(X-1)Thanks

Put all the equations in the standard form first, that is in the form of y = mx + c.
In that form, you get the slope directly by saying what the value of m is.
Can you give it a try?
Yes. But I need an example for me to fully understand it... do you mind giving me one?
okay so for the second one, which is Y=3X+7 is M=-7?
Not really. Notice that in the general formula, m is in front of x.
So, if you have y = mx + c, the gradient is m.
Which implies that if you have:
y = 2x + 1, the gradient is 2
y = 2 + x, the gradient is 1 (because you rearrange to get y = x + 2)
2y = 3 - 2x, you need first to put it in the form y = mx + c, that is, giving a gradient of -2/2 = -1.
Can you post what you got for all those equations to see if you got them right?
