Question 1018654

NEED ANSWERS PLEASE PLEASE!!

1. Sketch a graph of the relation y + 4 = 2(x – 3). Explain the procedure used.

2.   Sketch a graph of the linear relation 8x + 2y = 24. Explain the procedure.

3. Determine the value of B such that the line defined by 8x + By + 92 = 0 passes through the point (-4,12).
<pre><b><u>Nos. 1 and 2:</b></u>
1) Substitute 0 for x, and solve for y to determine the y-intercept point
2) Substitute 0 for y, and solve for x to determine the x-intercept point
3) Join the points to get the graph

<b><u>No. 3:</b></u>
8x + By + 92 = 0 ------ Substituting (- 4, 12) into equation
8(- 4) + 12B + 92 = 0
- 32 + 12B + 92 = 0
60 + 12B = 0
12B = - 60
{{{B = (- 60)/12}}}, or {{{highlight(highlight_green(highlight(B = - 5))))}}}
