Answer <u>(assuming it can be in slope-intercept format)</u>:
Step-by-step explanation:
When knowing the y-intercept of a line and its slope, we can write an equation representing it in slope-intercept form, or
.
1) First, find the slope of the equation. Use the slope formula,
, to find the slope. Substitute the x and y values of the given points into the formula and simplify:

Thus, the slope is
.
2) Usually, we would have to use one of the given points and the slope to put the equation in point-slope form. However, notice that the point (0,7) has an x-value of 0. All points on the y-axis have an x-value of 0, thus (0,7) must be the y-intercept of the line. Now that we know the slope of the line and its y-intercept, we can already write the equation in slope-intercept format, represented by the equation
. Substitute
and
for real values.
Since
represents the slope, substitute
in its place in the equation. Since
represents the y-intercept, substitute 7 in its place. This gives the following equation and answer:

Answer: The function that modes this situation would be: y = 475(1 + .0125)^x.
This is an example of an exponential equation. These equations are always in the form y = ab^x.
The a value is the starting value. The b value is the interest rate. The x value is the number of years.
The only thing to be careful about is the rate. We are adding 1.25% or 0.125. Make sure that you are adding 1 whole to the 1.25% and don't just use 0.125.
40 percent
Do 50/125 and you get 0.4 and that’s 40 percent.
