Write an equation for the line described. Give the answer in standard form. through (2,6), m= -5​
LiRa [457]

Answer:

  5x +y = 16

Step-by-step explanation:

Given a point and slope, it often works well to start with the point-slope form of the equation for a line:

  y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)

Your point and slope make this ...

  y -6 = -5(x -2)

  y -6 = -5x +10 . . . . . . eliminate parentheses

  5x +y = 16 . . . . . . . . . add 5x+6 to both sides; your standard form equation

You are using 0.05 gallons per mile of a SUV gas tank that holds 16 gallons. y = - 0.05x + 16. (Or, if you wish you may use

Here, we just use the following x values and put them into the equation.

y = - 0.05x + 16
y = -0.5(0) + 16
y = 16

y = - 0.05x + 16
y = -0.5(160) + 16
y = -80 + 16
y = -64

y = - 0.05x + 16
y = -0.5(320) + 16
y = - 160 + 16
y = -144

Now, to set up the table, you could list the x values and the y values. 

x values :- 0,160, 320
y values:- 16, -64, -144
