Find the equation of a line with slope 1/2 through the point (10,12)

mihalych1998 [28]

Answer:

$x-2y+14=0$

Step-by-step explanation:

$Slope \:( m) =\frac{1}{2}$

$(x_1 \:y_1) =(10, \:12)$

Equation of line in point slope form is given as:

$y-y_1 =m(x-x_1)$

Plugging the values of m and $(x_1 \:y_1)$ , we find:

$y-12=\frac{1}{2} (x-10)$

$2y-24=x-10$

$0=x-10-2y+24$

$x-2y+14=0$

This is the required equation of line.

X2 -5x+6 To solve a quadratic equation, start by factoring,

Y_Kistochka [10]

Answer:

$x=2$ OR $x=3$

Step-by-step explanation:

Given equation:

$x^2 -5x+6=0$

Solving the equation for 'x':

Using factorization method:

$x^2-2x-3x+6=0$

Making the factors by taking common:

$x(x-2)-3(x-2)=0\\(x-2)(x-3)=0$

$x-2=0\\\\x=2$

$x-3=0\\\\x=3$

Alborosie

2/3 = 0.66
7/8 = 3.38

- 7/8 is bigger because if you convert each of the fractions into decimals you will find your answer
