128 / 4 =32
Mr Bentleys tie is $32
Mr. Vander Heydens is $96
27 is the total. So you divide 15 by 27 = .55 so 55%
Ah well this would look like 2(30) + 30 = 90 aka 2L + W = 90
The line of best fit is given by the equation y = 1.56x - 4.105
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Plotting the points on a graph using geogebra online tool:
