The slope of the linear equation is 20 and the y-intercept is 150
<h3>What is a Slope?</h3>
Slope measures how steep a straight line is. It is described as rise over run.
The slope of the linear equation can be found as follows;
He opens the account with $150 and he plans to save $20 each week. Therefore,
let
x = number of weeks
Therefore,
where
y = amount in his account after x number of weeks.
Using the slope intercept equation,
<h3>Slope intercept equation:</h3>
where
m = slope
c = y-intercept
Therefore, the slope of the linear equation is 20 and the y-intercept is 150

Check the picture below.
and since a triangle has a sum of 180° for all interior angles.
A = 180 - 39.34 - 25
A = 115.66

make sure your calculator is in Degree mode.
0.25 is 1/4 if that's what youre asking, i'm not sure,
The answer is A = 2 tenths
C = .2
