Please help me! It wants me to give an equation for the line using y = mx + b

m = slope of the line
b = the y-intercept

y = - x -

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 4, 5) and (x₂, y₂ ) = (2, - 5) ← 2 points on the line

m = = = - , thus

y = - x + b ← is the partial equation

To find b substitute either of the 2 points into the partial equation

Using (2, - 5), then

- 5 = - + b ⇒ b = - 5 + = -

y = - x - ← equation of line

b, i believe, but not sure.

idk wbu
