Write the equation of a line that passes through (2,6) and (-2,2)
Viktor [21]

Answer:

y = x + 4

Step-by-step explanation:

The equation of the line is

y = mx + c

Step 1: find the slope

m = y2 - y1 / x2 - x1

Give points

( 2 , 6) ( -2 ,2)

x1 = 2

y1 = 6

x2 = -2

y2 = 2

m = 2 - 6 / -2 - 2

m = -4 / -4

m = 1

y = mx + c

y = 1x + c

y = x + c

Step 2: sub any of the two points given into the equation

( 2 , 6)

x = 2

y = 6

y = x + c

6 = 2 + c

6 - 2 = c

c = 4

Step 3: sub c into the equation

y = x + 4

The equation of the line is

y = x + 4

5x - 2 times 2x will equal the area of 'Potatoes.'

5x times 2x is 10x^2.

2 times 2x is 4x.

I cannot provide an exact value because x hasn't been identified.

How do u turn y +2=-3(x-1) Into standard form
Darina [25.2K]

Answer:

<h2>3x + y = 1</h2>

Step-by-step explanation:

y+2=-3(x-1)\\\\\text{It's a point-slope form of an equation of a line}.\\\\\text{The standard form is:}\ Ax+By=C.\\\\\text{Convert:}\\\\y+2=-3(x-1)\qquad\text{use the distributive property}:\ a(b+c)=ab+ac\\\\y+2=(-3)(x)+(-3)(-1)\\\\y+2=-3x+3\qquad\text{subtract 2 from both sides}\\\\y+2-2=-3x+3-2\\\\y=-3x+1\qquad\text{add}\ 3x\ \text{to both sides}\\\\y+3x=-3x+3x+1\\\\3x+y=1
