The slope-intercept form:

m - slope
b - y-intercept → (0, b).
We have the points (4, 7) and (0, 7) → b = 7.
Calculate the slope:

Therefore we have 
The standard form: 
<h3>Answer: y = 7.</h3><h3><em>It's a horizontal line.</em></h3>
Circumference of a circle = 2πr
Circumference of the whole circle= 2π(30) = 60π
360 - 90 = 270
Length XPY = 270/360 x 60π = 45π
Answer: 45π m
12 and 3/5 hope this helped
Answer:
B. Zero
Step-by-step explanation:
The slope of the line is in the the first two quadrants and is horizontal, meaning it has zero slope.
