SOLUTION: how do i find the slope & y-intercept of y=1.8x? & what does it mean when they say find an equation of the line containing the given point & having the given slope of (-3,0),m=-2?

Question 675865: how do i find the slope & y-intercept of y=1.8x? & what does it mean when they say find an equation of the line containing the given point & having the given slope of (-3,0),m=-2?
Answer by ReadingBoosters(3246) (Show Source): You can put this solution on YOUR website!
y = 1.8x
comparing to the y=mx+b slope-intercept format
slope, m, is 1.8
y intercept, b, is 0
...

...
When given the slope and a point, use the point-slope formula to determine the linear equation.
...
y-y1 = m(x-x1)
...
y - 0 = -2(x--3)
y = -2(x+3)
y = -2x + -6
