Question

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

Answer 1

x + y = −4

Answer 2

x + y = 4

Answer 3

x − y = −4

Answer 4

x-y=4

Answer 5

I need help learning how to solve this

Answer 6

standard form : Ax + By = C

In y = mx + b form, the slope is in the m position
slope(m) = -1
(-2,6)...x = -2 and y = 6
now we sub

6 = -1(-2) + b
6 = 2 + b
6 - 2 = b
4 = b

so your equation is : y = -x + 4..but we need it in Ax + By = C

y = -x + 4 --- add x to both sides
x + y = 4 <==== your standard form line
