What is an equation of the line that passes through the points (-7,-5) and
(-7, - 2)?

Step-by-step explanation:

x-coordinate of both points is the same. That means the line is parallel to Y-axis

Equation of every line parallel to Y-axis is: x = x₀  

where x₀ is the x-coordinate of any point from the line

x₀ = -7 so the equation is:

                                         x = -7

answer: 60

step-by-step explanation:

1/2a + (2/3×30)   = 50

1/2a + 20 = 50

1/2a = 30

a = 60
