Question 1194083

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
<pre>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) = (x<sub>1</sub>, y<sub>1</sub>) and (x<sub>2</sub>, y<sub>2</sub>)
         Use point (- 3, 0), and to get m, or slope, use slope formula: {{{matrix(1,4, m, "(slope)", "=", (y[2] - y[1])/(x[2] - x[1]))}}}.
c) HINT: He's <font color = red><font size = 4><b>WRONG</font></font></b>. Answer to this is NOT {{{cross(highlight(2x-7y+28=0))}}}
         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).</pre>
