Which equation best represents the line?

is the equation best represents the line.

Solution:

Take any two points on the line.

Let the points be (0, –4) and (4, 7).

General form of equation of a line is y = mx + c

where m is the slope and c is the y-intercept of the line.

y-intercept is the point which line crosses at y-axis.

In the given line, y-intercept is 4.

c = 4

Slope of the line:

Equation of the line:

y = mx + c

Hence is the equation best represents the line.
