Graph each equation y=7x-7how can you graph this

to graph a LINEar equation, since it's just a straight line, recall, to draw a straight line all you need is two points.

so we can just pick two random "x" values, h say x = 0, what's "y"?

y = 7(0)-7 => y = -7 so that gives us the point (0, -7)

hmmm x = 2, what is "y"?

y = 7(2) - 7 => y = 14-7 => y = 7 so we get the point (2, 7).

then just plot those, and run a line through them.

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
