Answer:
b = 20
Explanation:
Using the slope-intercept form, y = mx + b, as a reference:
slope = m
y-intercept = b
In your given linear equation, y= 15x + 20:
The slope, m = 15
And the y-intercept = 20.
The y-intercept is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.
Therefore, the value of the y-intercept, b, in the given equation is 20.
