D
Step-by-step explanation:
5x - 14y = -39
Change it to slope intercept form by solving for y.
subtract 5x from both sides first.
5x - 5x -14y = -39 -5x
The new equation is
-14y = -5x - 39
Divide each term by -14.
-14y/-14 = -5x/-14 -39/-14
The equation in slope intercept form is
y = 5/14x + 2.78
This is the only equation that has the most reasonable (positive) slope and the y-intercept of 2.78. The y-intercept is approximately half way between 5 and 0 and 2.78 satisfies that.
