Answer:
8
Step-by-step explanation:
this 3 qub root of 512 is 8
The line should equal 180 degrees, so we would subtract 122 from 180 to get 58 degrees. Since the triangle is equilateral, each angle is the same measure, so I believe m<1 should be 58 degrees.
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>
