Question
If m=3 and b=6, which is the correct slope-intercept equation?
- y=3-6
- y=3x-6
- y=3x+6
- y=6x+3
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=3x+6
Given m = 3 slope of the line and b = 6 intercept of the 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 3 for m and 6 for b]
⇒ y = 3x +6
So , y = 3x + 6 will be the right equation having slope as 3 and intercept as 6 .
Equation of line in slope intercept form is
y = slope.x + intercept .
