Question

Algebra Slope and intercept help?

Answer 1

1. Identify the slope and the y-intercept of the first equation. Describe how to graph this using the slope-intercept method.

Answer 2

How do I do this?

Answer 3

Well do you know the slope and what a y-intercept is?

Answer 4

I think the slope is the rate?

Answer 5

and the Y intercept is the variable that goes on the Y axis?

Answer 6

yup, slope in the equation: y=mx+b is "m"
\[m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} =\frac{rise}{run}\]

Answer 7

Y-intercept is when x=0

Answer 8

Okay :3 How can I solve for this with a fraction in the equation?

Answer 9

do I convert it into a decimal?

Answer 10

Well since it's a negative, the slope is negative.
\[-\frac{3}{2}=\frac{rise}{run}\]
Instead of going up 3, you go down 3 and over 2

Answer 11

And sorry, I know i'm an awful teacher >.<
