Solving the system of equations we get x=5 and y=10.5
Step-by-step explanation:
We need to solve the system of equations by substitutions.
The system of equations given are:
Let:
Putting value of y from eq(2) into eq(1)
So, value of x=5
Now putting value of x in eq 1 to find value of y:
So, value of y is 10.5
Solving the system of equations we get x=5 and y=10.5

The y-intercept is 2, and the x-intercept is -4 and 2 where the line segment crosses the y-axis and x-axis.
<h3>What is a straight line?</h3>A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
Where the line segment crosses the y-axis is the y-intercept,
And where the line segment crosses the x-axis is the x-intercept,
From the graph,
y-intercept is at (0,2)
x-intercepts is at (-4,0), (2,0)
Thus, the y-intercept is 2, and the x-intercept is -4 and 2 where the line segment crosses the y-axis and x-axis.
