Question
convert each equation below to slope - intercept form, then graph. show all work!
- $8x - 2y = -14$
- $x + y = 2$
- $6x + 8y = -32$
- $x - 2y = 0$
- $8x - 4y = 16$
- $3x - y = 3$
Response
Problem 13: \( 8x - 2y = -14 \)
Step 1: Isolate the \( y \)-term
Subtract \( 8x \) from both sides:
\( -2y = -8x - 14 \)
Step 2: Solve for \( y \)
Divide every term by \( -2 \):
\( y = \frac{-8x}{-2} + \frac{-14}{-2} \)
\( y = 4x + 7 \)
Step 1: Isolate \( y \)
Subtract \( x \) from both sides:
\( y = -x + 2 \)
Step 1: Isolate the \( y \)-term
Subtract \( 6x \) from both sides:
\( 8y = -6x - 32 \)
Step 2: Solve for \( y \)
Divide every term by \( 8 \):
\( y = \frac{-6x}{8} + \frac{-32}{8} \)
Simplify: \( y = -\frac{3}{4}x - 4 \)
