Answer:
A ray is a part of a line.
Step-by-step explanation:
yes
Answer:
y+8 = 2(x-4)
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes. Since we know the slope of the first line is -1/2, this means the slope of the line perpendicular to it is 2.
And since we know the coordinated located on the line, we can fill out the formula for poiny-slope form:
y-y1 = m(x-x1)
Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
We have the slope m = -1/5. Substitute:

Put the coordinates of the given point (-3, 7) to the equation:

<em>subtract 3/5 from both sides</em>
