The points given are:

(-1, -3) and (4, 2)

Coordinates are:

x₁ =-1 y₁=-3 x₂ = 4 y₂ = 2

First, let's find the slope(m) of the equation using the formula below:


m=(y_2-y_1)/(x_2-x_1)
=(2+3)/(4+1)=(5)/(5)=1

Next, find the inetercept of the equation by substituting x =-1 y=-3 m = 1 into y=mx+ b

-3 = 1(-1) + b

-4 = -1 + b

Add 1 to bothside

-4+1 = b

-3 = b

b = -3

We can now form the equation of the line by simply substituting the value of m and b into y=mx+ b

y = x - 3

Therefore, the equation of the line that satisfies the condition is y = x - 3
