Indicate the equation of the line, in standard form, that passes through (2, -4) and has a slope of 3/5. Enter your answer into
yulyashka [42]

The equation of the line is  y = (3/5)x + 26/5

<u>Step-by-step explanation:</u>

  • The line passes through the point (2,-4).
  • The line has the slope of 3/5.

To find the equation of the line passing through a point and given its slope, the slope-intercept form is used to find its equation.

<u>The equation of the line when a point and slope is given :</u>

⇒ (y-y1) = m(x-x1)

where,

  • m is the slope of the line.
  • (x1,y1) is the point (2.-4) in which the line passes through.

Therefore, the equation of the line can be framed by,

⇒ (y-(-4)) = 3/5  (x-2)

⇒ (y+4) = 3/5(x-2)

Take the denominator 5 to the left side of the equation.

⇒ 5(y+4) = 3(x-2)

Now, multiply the number outside the bracket to each term inside the bracket.

⇒ 5y+20 = 3x -6

⇒ 5y = 3x-26

Divide by 5 on both sides of the equation,

⇒ y = (3/5)x + 26/5

Therefore, the equation of the line is  y = (3/5)x + 26/5
