Formula for equation of a logbook passing through to points:

- where y1= -4 and x1= -6

Answer:
A: 26.89
B: 0.96
Step-by-step explanation:
70 percent of 250 is 26.89. 70 percent out of 3.20 is 0.96.
You can start by swapping the x- and y-coefficients and negating one. In standard form the x-coefficient must be positive, so it is convenient to choose that.
... 3x +y = ??
The ?? is a constant chosen to make sure the line goes through the given point. If you fill in 2 for x and -1 for y, you see what the constant needs to be.
... 3x + y = 3(2) +(-1) = 5
The equation is 3x + y = 5.
