The graph shows a system of equations:
Leviafan [203]

Answer:

c. (3, 2)

Step-by-step explanation:

Equating the values of y :

  • -x + 5 = x - 1
  • x + x = 5 + 1
  • 2x = 6
  • <u>x = 3</u> [x-coordinate of the solution]

Finding y by substituting x in one of the equations :

  • y = x - 1
  • y = 3 - 1
  • <u>y = 2</u> [y-coordinate of the solution]

Solving :

  • Solution = (x, y)
  • Solution = (3, 2)

A line passes through the points (1, 4) and (3, –4). Which is the equation of the line?
Vikentia [17]
Y = -4x + 8

First you need to find the slope of the line.

The slope formula is m = y2-y1/x2-x1

If you plugged in the points it would be m = -4-4/3-1

so m = -8/2 = -4

so the slope is -4

now we need to write the equation of the line

for this u use point slope form

the formula for that is y-y2=m(x-x1)

so if you plug it in it would be:

y-(-4)=-4(x-3)

now you solve

y+4=-4x+12

y+4-4= -4x+12-4

y = -4x + 8

and now you have the slope of the line

I hope this helps! :)
