Y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0)
We are told the slope is 4 so
y=4x+b, now using point (-7,-6) we can solve for the y-intercept...
-6=4(-7)+b
-6=-28+b
22=b so our line is:
y=4x+22
Maria ran farther because 3/4 is closer to a full mile than 3/8
Answer:
variable is a symbol which works as a placeholder for expression or quantities that may vary or change; is often used to represent the argument of a function or an arbitrary element of a set. In addition to numbers, variables are commonly used to represent vectors, matrices and functions.
