1.
Step-by-step explanation:
−2x - y = 9
x-intercept → Plug in 0 for <em>y</em><em> </em>to get −4½ for <em>x</em>
y-intercept → Plug in 0 for <em>x</em><em> </em>to get −9 for <em>y</em>
−2x - y = 9
+ 2x + 2x
_________
<em>Slope-Intercept</em><em> </em><em>Form</em>
_______________________________________________
x + 5y = 5
x-intercept → Plug in 0 for y to get 5 for x
y-intercept → Plug in 0 for x to get 1 for y
x + 5y = 5
- x - x
_________
<em>Slope-Intercept Form</em>
_______________________________________________
3x - 4y = 12
x-intercept → Plug in 0 for y to get 4 for x
y-intercept → Plug in 0 for x to get −3 for y
3x - 4y = 12
- 3x - 3x
_________
<em>Slope-Intercept Form</em>
