Write the slope intercept form of the equation through the given point with the given slope.
Sholpan [36]

Answer:

y = 3x - 4

Step-by-step explanation:

With the slope and a point, I can make an incomplete slope-intercept equation and solve for the y-intercept.

y=3x+b\\\\2=3(2)+b\\\\2=6+b\\\\2-6=6-6+b\\\\-4=b

The equation is:

y=3x-4

Solve x2 + 2x = 4 for x by completing the square. x equals plus or minus square root of 5 plus 1 x equals plus or minus square r
steposvetlana [31]

Answer:

x equals plus or minus square root of 5 minus 1

Step-by-step explanation:

we have

x^{2} +2x=4

Divide by 2 the coefficient of the x-term

2/2=1

squared the number

1^2=1

Adds both sides

x^{2} +2x+1=4+1

x^{2} +2x+1=5

Rewrite as perfect squares

(x+1)^{2}=5

take the square root both sides

x+1=(+/-)\sqrt{5}

x=(+/-)\sqrt{5}-1

therefore

x equals plus or minus square root of 5 minus 1
