| What is the real world meaning to A in the equation Y=A+bx the equation is Y=0.1469x+49.243 this is about roller coasters. answer key- |
Y=A+bx
.
Just as a matter of practice an equation of this type is normally written with the term
containing the x appearing first on the right side. So it is normally written as:
.
Y = bx + A
.
This form is called the slope-intercept form.
.
The A is the value of Y where the graph of the equation crosses the Y-axis.
.
and furthermore b is the slope of the graph, where slope is defined as the change in the
vertical Y distance divided by the corresponding change in the horizontal x distance.
The bigger that b is the steeper the slope.
.
You provided the equation:
.
Y=0.1469x+49.243.
