(1)The vertical line through (-5, 3).
(2) The line with x-intercept -3 and y-intercept 4.
----------------------------------------------------------
Only simple clear understanding of English language and knowing what is an ordered pair. x-intercept, where line shares point with x-axis. y-intercept, where line shares point with y-axis


-------------------------------------------------------------
(3) Line through (-8, 5) and parallel to the line 2x-7y+4=0
-------------------------------------------------------------

The coefficients on x term and y term are the same as for your given equation, but try this way:
2x-7y%2B4=0
2x-7y=-4
and for the point requested for line sought to go through, right side member is no longer -4;
2x-7y=2%28-8%29-7%2A5
2x-7y=-16-35
2x-7y=-51
and to keep with the same equation form as the given,
highlight%282x-7y%2B51=0%29

Find the equation of

(1)The vertical line through (-5, 3).
(2) The line with x-intercept -3 and y-intercept 4.
(3) Line through (-8, 5) and parallel to the line 2x-7y+4=0
For you to LEARN, you need to find the equations yourself.

a) HINT: Equation of a line: y = mx + b. Point: (- 5, 3)  ;   m (slope): UNDEFUNED.

b) HINT: Equation of a line: y = mx + b. Points: (- 3, 0) and (0, 4) = (x1, y1) and (x2, y2)
         Use point (- 3, 0), and to get m, or slope, use slope formula: .
c) HINT: He's WRONG. Answer to this is NOT cross%28highlight%282x-7y%2B28=0%29%29
         You're given an equation. The one being sought has the same slope, or m. 
         You're given a point, so use above hint to get your equation
         OR
         Shortcut to this answer: 2x - 7y = 2(- 8) - 7(5).

Find the equation of

(1)The vertical line through (-5, 3).
=============================
Define "vertical line."
Is it parallel to the y-axis on the x-y plane?
Is it parallel to the z-axis in a 3 dimensional x-y-z system?
