Answer:
y = 3x + 6
Explanation:
The equation of line is given as:
y = mx + b
Where
m is the slope, and
b is the y-intercept (y-axis cutting point)
- Given the slope is 3, we substitute 3 into m
- Given y-intercept is (0,6), we say that x = 0 and y = 6, the intercept (b) is basically 6. So we substitute 6 into b.
Now, we have our values, substituting, we get:
y = mx + b
y = 3x + 6
This is the equation of the line.
