51% less.
The length is decreased by 50%, which is the same as being multiplied by 0.5, then it's increased by 40% which is another multiplication by 1.4. So the overall change is 0.5 * 1.4 = 0.7, or the newest rectangle is 70% of the size of the original rectangle. And since the area increases by the square, the newest rectangle has 0.7 * 0.7 = 0.49 of the area as the original rectangle. So it has 51% less area than the original rectangle.

Answer:
y= 5/4x - 2
Step-by-step explanation:
Hey!
<u>Slope-Intercept Form</u> is y = mx + b, where <u>m</u> is the <u>slope</u> and <u>b</u> is the <u>y-intercept.</u>
First we can <em>locate the y-intercept</em>, or where the line passes through the y-axis.
The y-intercept is -2.
<em>Substitute </em>in the Slope-Intercept Form Equation:
y = mx -2
<u>Pick another point and substitute its x and y values in this equation.</u>
I chose (5,2) and substituted as 2 = m(5) -2
<em>Isolate </em>m:
<em>Add </em>2 to both sides <u>[Addition Property of Equality</u>]
2 + 2 = 5m - 2 + 2
4 = 5m
<em>Divide </em>by 5<em> </em>on both sides. [<u>Division Property of Equality</u>]
5m/5 = 4/5
m=4/5
<em>Substitute </em>in Slope-Intercept Form Equation.
<u><em>The Equation in Slope Intercept Form is y = 4/5x - 2</em></u>
