By using the graph (see attachment), the coordinates of the y-intercept of the parabola is (0, 7).
<h3>What is a graph?</h3>A graph can be defined as a type of chart that's commonly used to graphically represent data points on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.
In Mathematics, the y-intercept of any graph (parabola) occurs at the point where the value of "x" is equal to zero (0).
By critically observing the graph (see attachment), the coordinates of the y-intercept of the parabola is given by:
y-intercept = (0, 7).

Mr. Jenson needs 250 square tiles of dimensions 12 cm which cover 3.6 square metres walkway.
What is the area of Square?
The area of a square is the product of the length of each side with itself, i.e. Area A = s x s where s is the length of each side of the square.
Mr. Jenson wants to tile 3.6 sq. meters or 36000 sq. cm.
Total number of tiles is 250.
Area of tile = = 36000/ 250 = 144 sq. cm
s X s = 144 sq. cm
s = cm
s = 12 cm
Thus, Mr. Jenson needs 250 square tiles of dimensions 12 cm which cover 3.6 square metres walkway..
