Help? ^-^ WILL GIVE BRAINLIEST! What is the slope of a line through (1, 3) and (-2, 2)?

ryzh [129]

Answer:

The slope of the line is $\frac{1}{3}$

Step-by-step explanation:

The Slope of a Line

Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the formula:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

It's given the points (1,3) and (-2,2). Let's calculate the slope:

$\displaystyle m=\frac{2-3}{-2-1}$

Calculating:

$\displaystyle m=\frac{-1}{-3}$

$\displaystyle m=\frac{1}{3}$

The slope of the line is $\frac{1}{3}$

solve 2x2 12x − 14 = 0 by completing the square. 2(x 6)2 = 26; x = −6 square root 13, x = −6 − square root 132(x 6)2 = 20; x = −

coldgirl [10]

Assuming that the blank space is a plus
2x^2+12x-14=0

isolate x
(2x^2+12x)-14=0
undistribute 2
2(x^2+6x)-14=0
take 1/2 of 6 and square and add negative and positive
2(x^2+6x+9-9)-14=0
factor perfect squrae
2((x+3)^2-9)-14=0
distribute
2(x+3)^2-18-14=0
2(x+3)^2-32=0
2(x+3)^2=32
divide 2
(x+3)^2=16
sqrt
x+3=+/-4
minus 3
x=+/-4-3
x=-7 or 1
2nd to last option
