Someone please help me...

Simplify following expression: 1/2(10y + 4) + 3

What is the slope of the line shown below?

Which equation is y = -6x2 + 3x + 2 rewritten in vertex form?

Four equations are shown below.equation 1: y=2*equation 2: y=2x-5equation 3: y=x2 + 6equation 4: tdentify one linear equation and one nonlinear equation from the list.why each equation you identified is linear or nonlinear.nd one nonlinear equation from the list. state a reasonlinear equation
