Use the slope-intercept form of a line, y-yp=m%28x-xp%29, and then convert to slope-intercept form,y=mx%2Bb.
y-%28-10%29=-2%28x-6%29
y%2B10=-2x%2B12
highlight%28y=-2x%2B2%29

Use y = mx + b
-10 = (-2)*6 + b
b = 2 (the y-intercept)
-----------
--> y = -2x + 2 is the equation

THe slpoe is -2 and it passes through (6,-10)
How would you find the y intercept.
What is the equation of the line
Given the standard equation
y = mx + b

where b = the y intercept
m = -2
x = 6
y = -10

-10 = -2(6) + b
b = -10 + 12
b = 2
The y intercept is 2
