Answer:
Step-by-step explanation:
The equation of the line is Slope-intercept form is:
Where "m" is the slope and "b" the y-intercept.
The slopes of perpendicular lines are negative reciprocal.
Then, if the slope of the first line is -3, the slope of the other line must be:
Substitute the point (3,4) into the equation and solve for b:
Then the equation of this line is:
The graph that represents the linear equation is attached below.
<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.
