Question

Write an equation for the line that passes through (0, -2) and whose slope is ½.


y = 1/2x + 2

y = -1/2x -2

y = 1/2x – 2

y = -2x + ½

Answer 1

answer only plzzz

Answer 2

(0, -2) = y intercept=c=-2
y=0.5x-2

Answer 4

It's really much faster if you understand it yourself...

Answer 5

can you explain it for me plzzz

Answer 6

ok
m means the slope and can be determined if you're given two points with the slope equation
\[m=\frac{y_2-y_1}{x_2-x_1}\]

b means the y- intercept
y intercept means the point that lies on the y-axis
so they always come in the form of (0,b)

there are 3 different forms you need to understand when doing these types of problems

the first is the slope intercept form
\[y=mx+b\]
the second is the point slope form
\[y-y_1=m(x-x_1)\]
the last one is standard form
\[Ax+By=C\]

since you were given the slope and a point
you can substitute those into the point slope equation and then solve for y

or you could've realized that the point given was a y intercept and substituted the slope and intercept into the slope intercept form

both methods would give you the same answer

omg thank you
