If the representation is a graph then use the vertical line test. Draw or imagine straight vertical lines going down the graph. If the vertical line only goes through the function line one time then it is a function. For an example, a circle on a coordinate plane is not a function but a wavy line is.
If the representation is a table with points then look at the x values. If x repeats then it is not a function.
It would be 4.25 plus 4.25 and that will equal 8.5
Answer:
The slope intercept form would be y = 3/4x - 4
Step-by-step explanation:
To find the slope intercept form of this line, we start with using our given information in point-slope form. Then we solve for y.
y - y1 = m(x - x1)
y - 2 = 3/4(x - 8)
y - 2 = 3/4x - 6
y = 3/4x - 4
That true because a giraffe had 4 legs.
