To multiply whole numbers and fractions, multiply the numerator by the whole number. Example: 1/3×4= 4/3=1 1/3
Answer:

Step-by-step explanation:
First we need to rewrite 3x-5y=8 in slope-intercept form.

The slope of this line is

The line perpendicular to this line will have a slope that is the negative reciprocal of 3/5, which is

This line passes through (3,7).
The equation is given by:

We substitute the point and slope to get:

We multiply through by 3 to get:

Expand to obtain:



The slope is (8-2)/(0-2)=-3
the y intercept is 8
the equation is y=-3x+8
the area to the left is shaded, and the line is solid, so y

-3x+8
You just have to divide the bigger x value by the smaller x value
-8.4/-2=4.2
