Write an equation in slope intercept form of the line that passes through (-2,10) and (1,1).

Step-by-step explanation:

The slope of a line passing through two points: (x₂, y₂) and (x₁, y₁) is:

(-2, 10)  ⇒  x₁ = -2,  y₁ = 10

(1, 1)    ⇒  x₂ = 1,  y₂ = 1

So:

The point-slope form of equation of line is y - y₀ = m(x - x₀)

We can pick any of given poins, so:

x₀ = 1,  y₀ = 1   and  m = -3

y - 1 = -3(x - 1)

y = -3x + 3 + 1

y = -3x + 4      ←  slope intercept form of the line
