Which is the graph of the system of inequalities y > 4/5 x – 1/5 and y < 2x + 6
2 answers:
Answer: The coefficient of x tells you the slope.
The constant tells you the y-intercept.
Step-by-step explanation: see the attachment
Step-by-step explanation:
firstly in equation y= 2x+6 suppose the value of y as zero and find the value of x. again suppose the value of x as 0 and find the value of y. Do the same for other equation as well and you get two values of X and y.
Also find the slope of each equation by the formula :
slope= - coefficient of x / coefficient of y. and solve by plotting the points according to the slope.

Answer:
Step-by-step explanation:
Let
d ------> the number of days
c -----> the cost
we know that
The cost is equal to the number of days multiplied by $2 per day plus the initial fee of $5
The linear equation in slope-intercept form is
where
m is the slope
b is the c-intercept (value of c when the value of d is equal to zero)
in this problem we have
m=$2 per day
b=$5
