Which form most quickly reveals the y-intercept? Answer is B
What is the y-intercept? Answer is 24
Step-by-step explanation:
It is pretty simple. For the first question, you have standard form, factored form and vertex form. With factored form you have all the quadratic equation in the form ax²+bx+c making the y = g(x) simple to understand.
For the second one, we know that y-intercept is when the slope crosses the y-axis. So we know that our slope must have x equal to 0 and you substitute 0 to x...
You plug -x+16 in for y in x+4y=37 to get x after you multiply x+4y=37 by -1. -x-4(-x+16)=-37 -x+4x-64=-37 3x-64=-37 3x=27 x=9 Then you plug 9 into either equation to get y. y=-x+16 y=-(9)+16 y=7
