Answer:
<em>x - 5y = - 10 </em>
Step-by-step explanation:
y = mx + b (b is y-intercept)
m =
~~~~~~~~~~~~
x + 4y = 8 ⇔ y =
x + 2 ⇒ y-intercept is 2 and coordinates of y-intercept are <u><em>(0, 2)</em></u>
(5, 3)
m =
=
y =
x + 2 (slope-intercept form)
<em>x - 5y = - 10</em> (standard form)
it should be 2× + y= -4
hope this helps :)
Well you estimate the equation. 7 x 3289 to 7 x 3000 and you do 7 x 3 but add 3 zeros in the end so you get 21000
