Step-by-step explanation:
Slope-intercept form: y=mx+b
The slope is 8. This means that 8 multiplied by x is the slope of the line, and if there was no y-intercept then the first point would be (1,8) so 8 would be unit rate.
The y-intercept is -12. This means that though the slope of the line would still be 8, you move the point down on the y-axis by 12. The y-coordinate will always be 12 less than 8 times x
We have been given that . We are asked to prove that .
First of all, we will solve for tangent of alpha as:
Now, we will divide left side of our given equation by as:
We know that , so we will get:
Upon substituting , we will get:
Hence proved.
-1 because a positive plus and negative will be a negative answer
5 1.2
-3 7
6 1.2
2 -3
yes its a function, as long as the domain (input) doesnt have the same number with two different ranges (outputs) its a function
