Question

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

Answer 1

Use the point slope form first, and substitute in the values that are given to you.
y - y1 = m (x-x1)
y + 3 = 1/2 (x +2)
NOW, we can just simplify this equation so that it's in slope intercept form.
You would distribute out the brackets first, and then just reorder the terms.
y + 3 = 1/2x + 1
y + 3 - 3 = 1/2x + 1-3
y = 1/2x -2
Which is now in slope intercept form. x

Answer 2

Thank you

Answer 3

Sorry but the answers are either
2x+y=4
2x-y=4
x+2y=4
x-2y=4
