Perpendicular
Bit confusing but that should be right
Answer:
The method used is substitution method
x = 2, y = -6
Step-by-step explanation:
Given the simultaneous equation
Y = −3x ..... 1
4x + y = 2 ... 2
Substitute equation 1 into 2
4x + (-3x) = 2
4x - 3x = 2
x = 2
Get y:
y = -3x
y = -3(2)
y = -6
<em>Hence the value of (x, y) is (2, -6)</em>

<h3>How to Interpret the Equation of a Linear Graph?</h3>
A linear graph can be modelled by an equation in slope-intercept form, as: y = mx + b. Here, we have:
- m as the slope value = change in y / change in x
- b as the y-intercept which is the point on the y-axis that the line intercepts which is also the starting value/initial value.
Given the linear equation, y = 5x + 10, it means the slope of the graph that represents this equation would be 5, while the line that intersects the y-axis would be at 10.
In the graph attached below, the slope is 5, and the y-intercept is 10.
Therefore, the graph that represents the linear equation is attached below.
