| Question 387209:  y=x2+4x+3  Graph using Quadratic Equation.  I have a calculator but I really don't know how to use it well. I know how to go to the Y= screen. How do you set this up and graph it.
 
 
 I have one more question, Question Solve with the slope-intercept form of equation (-7,7) and(0,-3).
 this is what I got.
 (-7,7) (0,-3)
 m=7-3/0-7
 =4/-7=4/7
 y=(4/7)x+b
 using (0,-3) to solve for b
 -3=b
 y=(4/7)x-3 my answer

You can put this solution on YOUR website! I think you lost a minus sign somewhere. m=(-3-+7)/(0--7)
 m=-10/+7
 m=-10/7
 ----------------
 y=-10/7x-3
 make sure my work is good.
