what is the equation for slope intercept
y=mx+b
If a slope is positive is it going up or down to the right
up
10x+25=150
x=12.5
what is y intercept
The y value when your x is 0
negative slope means it is going what way.
down
25x+300=500 solve for x
x=8
how do you get slope from 2 points.
y2-y2 / x2-x1
what does a -y intercept mean
The y is less than 0 when x =0
13x+23=114
x=7
what is the equation for point slope
y-y1=m(x-x1)
what is a slope with 0 as a denominator called
undefined
19x-65=239
x=16
what is standard form's equation
Ax+By=C
what is the origon of a graph
0,0
243x+ 29=2216
x=9
