Answer:
y = 4x +3
Step-by-step explanation:
The slope formula can be used to find the slope:
m = (y2 -y1)/(x2 -x1)
Using the first two lines of the table, we find the slope to be ...
m = (11 -7)/(2 -1) = 4/1 = 4
__
The y-intercept can be found from the relation ...
b = y -mx
Using the slope we found, and the first line of the table, we find the intercept to be ...
b = 7 -4(1) = 3
__
Then the equation is ...
y = mx +b . . . . . . slope-intercept form of the equation for a line
y = 4x +3
Well, the base and height would still be applicable (essentially, base is just width and height is just, uh, height,)
So basically the area of one triangle is 0.5(7*6), which is 21
The area of one triangle is option c., 21.
The answer would be D. H<span>ow long are the songs you practice playing on your instrument?
Statistical questions are ones that will show variability. The first three questions will have a straight answer. The last one however will have data that varies, since most likely every song is not the same length.
