Is means equals and of means multiply
W = 30% * 31
Change to decimal form

Depends on what the length and the width is.
Answer:
y = (1/2)x + 3
Step-by-step explanation:
The points are separated by 1 vertical unit for each 2 horizontal units, so the slope of the line through them is ...
slope = vertical change / horizontal change = 1/2
There is a point on the y-axis at y=3 where x=0, so we know the y-intercept of the line is 3. Then, in slope-intercept form, the equation of the line can be written ...
y = slope · x + y-intercept
y = (1/2)x + 3
