Brian correctly used a method of completing the square to solve the equation x2+7x-11=0. Brian's first step was to rewrite the equation as x2+7x=11. He then added a number to both sides of the equation. Which number did he add?

The answer is actually 49/4

Step-by-step explanation:

47

step-by-step explanation:

hi there

the slope is 1/3.

this is because from the y-intercept, you go up one, and you go to the right three, to get to the next exact point on the graph. this is known at the “rise over run.”

p.s. (if you need it).your y-intercept is -2, because that is the point on the graph where the line crosses the y-axis.

hope that : )
