ANSWER
EXPLANATION
We want to find the equation of the straight line given on the graph.
The general form of a linear equation is given as:
where m = slope; b = y-intercept
To find the slope, we apply the formula for slope:
where (x1, y1) and (x2, y2) are two points on the line
Let us pick (1,2) and (4,4)
Therefore, the slope is:
To find the equation, we now apply the point-slope formula:
Therefore, we have that the equation of the line is:
That is the equation of the line.
Answer:
B
Step-by-step explanation:
351 children and 308 adults swam at the public pool.
Step-by-step explanation:
Let,
Children = x
Adults = y
Price per children = $1.75
Price per adult = $2.00
According to given statement;
x+y=659 Eqn 1
1.75x+2y=1230.25 Eqn 2
351 children and 308 adults swam at the public pool.
