Answer:
The y-intercept of the line is 2
Step-by-step explanation:
You could try to find the slope of the line and then find the intercept with y axis by sloving b = y - ax
But here it seems easy enough once you see that the x values in the table increase by a factor of 8 and the y values in the table increase by a factor of 20.
(By the way, this is enough to give you the slope, because it is 8/20 ). But why bother?
Just extrapolate the table to the left, and you will find the y value where x = 0
x 0 8 16 24 32
y 2 22 44 64 84
So the y-intercept of the line is 2.
Extra:
The full equation of the line is:
y = 8/20x + 2
Slope=-4 or -4/1
Work:
(2, 5) (3, 1)
x1 y1. x2 y2
M= y2-y1/x2-x1
M= 1-5/3-2
M= -4/1
M=-4
Assuming that you mean 5x(2-3) for your equation, you would just have to plug 2 into where x is. This makes your equation 5*2(2-3). This gives you 10(-1) because 5*2=10, and 2-3=-1. Then simply multiply the two to get:
-10
