The 1st one is 6, 2nd: 2.
Given equation is y=3x+3 and 
Let's simplify the 2nd equation
before we can start graph so that calculation will be easy

multiply both sides by 3 to cancel out fractions

y=3x+3
which is exactly same as the first equation so graph of both will be exactly same and solution will be infinitely many solutions.
y=3x+3 has y-intercept 3 so first point will be (0,3). Slope is 3 so rise 3 unit up then 1 right and graph the new point.
3×2=692047 82837=284749×2484r133.e9274
It’s a semicircle, so it would be 1/2 pi r^2.
They are terms<span> that contain the same variables raised to the same power. Only the numerical coefficients are different. In an expression, only </span>like terms<span> can be combined. We combine </span>like terms<span> to shorten and simplify algebraic expressions, so we can work with them more easily.</span>
