Lets so your points are (2,-5) and (8,2) You first find "m" or the slope. You do y2-y1 over x2-x1 So it would be 7/6. So your slope is 7/6. Now to find he y intercept. You do Y=7/6x+b you can do whatever point. I prefer using the first one. So it would be -5=7/6(2)+b Times 7/6 with 2. You should get 2.3 Then subtract. -5-2.3 And your y intercept is -7.3 :) Happy to help!

How do you find slope if the points aren't given?
the slope is the 'm' in y=mx+b so even if the points aren't given, if there is an equation, then you can find the slope. for example, if you have an equation like this: y=2x+5 the slope is 2 and the y-intercept is 5.
What is the equation in slope intercept form with a slope of -3 and points 4-5?
y = -3x + 7 Slope-intercept form is y = mx +b where m is slope and b is the y-intercept when x=0 Given that the slope is -3, this becomes y = -3x + b Substituting the given point (4,-5) we get -5 = -3·4 + b = -12 + b which we can solve to find that b =7
How do I find the y-intercept if the line passes through negative 2 and 3?
You can't. There are an infinite number of lines that pass through the point (-2, 3).They all have different y-intercepts and different slopes.In order to narrow it down to a single line, you have to give more information.One more point would do it.=======================================================Here's the minimum information needed to define a unique line:-- you name 2 points; I find slope, intercept, and all other points.-- you name one point and one intercept ... 'x' or 'y'; I find slope and all other points.-- you name x-intercept and y-intercept; I find slope and all other points.-- you name one point and the slope; I find intercept and all other points.-- you name one intercept and the slope; I find all other points.
How do you find the slope intercept form of an equation that passes through the points 8 and 2 and 2 and 2 and 1 and 2?
It is a straight line with no slope with a 'y' intercept of 2
What is the slope intercept for (1012)(-216)?
To find the slope intercept a pair of coordinates are needed in the form of (x1, y1) and (x2, y2) of which none have been given that makes sense.
