Question
Write the equation of a line with a slope of 2 and y-intercept of -5.
- y = 5x - 2
- y = 2x - 5
- y = -2x - 5
- y = 2x + 5
Hint:
Given the slope of line as m and intercept as b .
the Equation of line will be y = mx + b .
The correct answer is: y = 2x - 5
Given the slope of line = 2 and intercept = -5
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 :
⇒ y = 2x -5 [substituting 2 for m and y for -5]
So , y = 2x -5 is the equation of line .
Equation of line in slope intercept form is
y = slope.x + intercept .
