Question

# If the slope of a line is and the y intercept is -3, write the equation of the line.

- y = 2/3x - 3
- y = 2/3x + 3
- y =-2/3x - 3
- y = 2/3x + 3

Hint:

### Given the slope of line as m and intercept as b .

the Equation of line will be y = mx + c .

## The correct answer is: y = 2/3x - 3

### Given m = 2/3 and b = -3

equation of line =?

Step 1 : Using the slope and y-intercept of the line to write the equation of the line.

Slope-intercept from of equation of a line is y = mx +b

Step 2 : [substituting 2/3 for m and -3 for b]

y = 2/3x -3

so, y = 2/3x -3 is the equation of line.

Equation of line in slope intercept form is

y = slope.x + intercept .
