Question 217201
find the x and y intercepts of each line and write the equation in standard form:
 y = {{{2/7}}}x - 1
:
Find the y intercept (occurs when x = 0)
 y = {{{2/7}}}(0) - 1
y = -1
:
Find the x intercept (occurs when y = 0)
{{{2/7}}}x - 1 = 0
{{{2/7}}}x = + 1
multiply both sides by 7
2x = 7
Divide both sides by 2
x = {{{7/2}}}
x = 3.5
:
Write in standard form
 y = {{{2/7}}}x - 1

Subtract {{{2/7}}}x from both sides
 y - {{{2/7}}}x = - 1

Multiply by -7, (gets rid of the denominator and changes the signs)
-7y + 2x = + 7

which is the standard form
2x - 7y = 7
