Alejandra correctly wrote the equation y-3=1/5(x-10) to represent a l8ne that her teacher sketched. The teacher then changed the

line so it had a slope of 2, but still through the same point. Which equation should Alejandra write to represent the new line ?

Answer: It would be y-3=2(x-10)

Step-by-step explanation:

Since Alejandra's teacher said that it had a slope of 2, in the equation y-y1=m(x-x1), the m, is the slope, therefore, the m is a slope of 2.

Hope this helped.

Answer:

Point B

Step-by-step explanation:

Lines given:

  • y= 2/5x - 1/2
  • y= -1/3x +2/3

x coordinate of intersection of given lines is:

  • 2/5x - 1/2= -1/3x+2/3
  • 2/5x+1/3x= 2/3 +1/2
  • 6/15x+5/15x= 4/6+3/6
  • 11/15x=7/6
  • x= 7*15/11*6
  • x= 35/22

For this value of x, the value of y is:

  • y= 2/5*35/22 - 1/2
  • y=14/22- 1/2
  • y= 3/22

As per graph point (35/22, 3/22) is point B
