Question 1049530: give the equation of this line in slope intercept form, the slope is -3, passes through (4,-1), y=3x+, i'm not sure what to do Found 2 solutions by Edwin McCravy, MathLover1:Answer by Edwin McCravy(20063) (Show Source):
y = mx + b, where m is the slope -3 and b (unknown) is
the y-coordinate of the y-intercept.
y = -3x + b
It passes through (4,-1),
So the equation is true if we substitute x=4 and y=-1
-1 = -3(4) + b
-1 = -12 + b
11 = b
Now we substitute b = 11 in y = -3x + b
y = -3x + 11
That's the equation of the line
We get some points
x | y
0 |11
2 | 5
3 | 2
5 |-4

You can put this solution on YOUR website!
the equation of this line in slope intercept form is where is a slope and is -intercept which i a point (,)
if the slope is ,means
then we have
if the line passes through (,)=(,), use it to find ...........plug in for and for
and your equation is:
check it on a graph:
