Question

graph the equation by plotting 3 points
-2x - 3y=-7

Answer 1

Since equation is linear. You can plot in any three values for x and find the corresponding y values. Lets use x = -1, 0, and 1

-2(-1) - 3y =-7
2 - 3y = -7
y = 9/3
------
-2(0) - 3y = -7
-3y = -7
y = 7/3
-------
-2(1) - 3y = -7
-2 - 3y = -7
-3y = -5
y = 5/3

Therefore three points = (-1, 3) & (0, 7/3) & (1, 5/3)

Just a stab in the dark here hope its okay?

Answer 2

it has to be whole numbers
