+257 What is the slope of the line passing through the points (0, −5)(0, −5) and (4, 2)(4, 2) ?
With this question plz and just tell me the answer Plzz

It would be a good idea for you to watch and try and understand this video :)

or possibly this might be easier to understand

+118658 Tell me when you have had a good look at these sites Snowwolf.
If it is all beyond you just say so and I will try to be more helpful.
But it would be good if you can learn from other examples :)
+37101 Do you know how to find the SLOPE of the line????
the equation of a line is of the form y = mx + b where 'm' is the slope of the line.
Slope is defined as rise / run = (y1-y2) / (x1-x2)
So let's sub in the coordinates you are given
(-5-2) / (0-4) = -7/-4 = 7/4 = slope = m
So far you have y = 7/4 x + b
If you substitute one of the sets of numbers in this equation you can find 'b'
y=7/4 x + b
-5 = 7/4 (0) + b
b= -5
So now your line equation is y = 7/4 x - 5 Substitute point (4,2) in there to see if it is correct !
2 = 7/4(4) -5 Check !
