Question

What is the equation in standard form of the line which passes through (–2, –3) and has a slope of 1/2?

a) 2x+y=4
b) 2x-y=4
c) x+2y=4
d) x-2y=4

Answer 1

you can use the formula \[y - y_1 = m(x-x_1)\]

Answer 2

Use point-slope form
\[y - y _{1} = m(x - x _{1}\]
y + 3 = 1/2(x + 2)
Standard form is Ax + By = C
y + 3 = 1/2x + 1
Get it into standard form.
1/2x - y = 2
x - 2y = 4
