Question

What is the equation in standard form of the line which passes through (–2, 6) and has a slope of –1?

x + y = –4

x + y = 4

x – y = –4

x – y = 4

Answer 1

important equations you need to remember
slope equation
\[m=\frac{y_2-y_1}{x_2-x_1}\]

standard form
\[Ax+By=C\]

Point-slope form
\[y-y_1=m(x-x_1)\]

Slope intercept form
\[y= mx+b\]
b is the y intercept

Answer 2

substitute your values into point slope form, then solve for standard form
