Decreased height = 10 x \frac{100 - 25}{100}

                              = 10 x \frac{75}{100}

                              = \frac{750}{100}

                              = 7.5 cm

Answer:

7.5 cm

Step-by-step explanation:

Decreased height = 25% of 10

                              =\frac{25}{100}*10\\\\=0.25*10\\=2.5

New height = 10 - 2.5 = 7.5 cm

Write the equation of the line in slope-intercept form.
Alex Ar [27]
The answer is B.
Slope-intercept line is written as:
y=mx+b
m=slope
b=y-intercept
4 is the y-intercept because the line crosses the y-axis at 4.
The slope is -2 over 5, because slope is written as y over x.
So, if you start at the point at the 4, count 2 spaces down and 5 spaces right. The line crosses the point exactly, which is how you know the slope is accurate.
