Step 1 :

The standard form of a straight line is in the form y = m x + b

Step 2:

Recall on how to find the slope of  a line from two points

Slope is 3

Step 3:

Plug in the given values to find the slope intercept b

Take the first set (-1,4 ) as (x,y) and m = 3

-4 = 3 + b

b = -7

Step 4 :

Write the equation of a straight line

Plug in the values of m = 3 and b = -7 to get

y =  3 x - 7
