What equation is solved by the graphed systems of equations? 7x + 3 = x + 3 7x − 3 = x − 3 7x + 3 = x − 3 7x − 3 = x + 3

Is each relation a function? if so, state whether it is one-to-one or many-to-one. 3. (-4,7), (-3,5), (1,4), (3,-8), (5,-11) 4. (-4,8), (-2,4), (0,1), (2,4), (4,8) 5. (-2, 1), (-2,3), (0,-3), (1,4), (3,1)

Idon’t understand! use slope intercept form to solve: through: (2,5) slope= undefined

How do the definitions, properties, and postulates you've learned about line segments, parallel lines, and angles to define the shapes of polygons
