Using the graph, determine the coordinates of the y-intercept of the parabola. TT help
1 answer:
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).

Answer:
The constant of variation is $1.50
Step-by-step explanation:
Given
Point 1 (1,2)
Point 2 (5,8)
Required
Constant of Variation
Though the graph would have assisted in answering the question; its unavailability doesn't mean the question cannot be solved.
Having said that,
the constant variation can be solved by calculating the gradient of the graph;
The gradient is often represented by m and is calculated as thus
Where
By substituting values for x1,x2,y1 and y2; the gradient becomes
Hence, the constant of variation is $1.50
