The data is equally spaced in x so let's start by taking first differences.
4-9 = -5
-1-4 = -5
-6 - -1 = -5
-11 - -6 = -5
Hmmm. I detect a pattern. That tells us we have a line and the slope is -5.
We read off the y intercept from x=0 as -1.
So our equation in slope intercept form is
y = -5 x - 1
or as a function
Answer:
Step-by-step explanation:
A line has the following slope-intercept equation:
In which a is the slope.
Write the equation of a line that has a slope of -3 and passes through the point (1.25, -4).
Slope of -3 means that . So
Passes through the point (1.25, -4). Means that when
So
