What is the slope and y-intercept of y= 3x+6
Consider the equation y=3x+6 and determine what the y-intercept and slope
Recall that the slope-intercept form of a linear equation is:
y = mx + b , where 'm' is the slope of the line and 'b' is the y-intercept.
y = 3x + 6 ==> m = 3 , b = 6
Thus, the slope of the line is 3 and the y-intercept is 6.
The y-intercept is when the line crosses the y-axis, so when x = 0
y = 3(0) + 6 = 6, so the y-intercept is 6
the slope is 3, as you know y = mx + b, m is the slope
