Q. Which of the following is true of the graph is 9y−6x=1 in the XY-plane?
Rewrite Equation: Rewrite the equation in a more familiar form.To understand the graph of the equation 9y−6x=1, we can rewrite it in slope-intercept form (y=mx+b), where m is the slope and b is the y-intercept.9y=6x+1Multiplying both sides by 9 to get rid of the fraction, we get:y=(69)x+9
Simplify Further: Simplify the equation further.We can simplify the slope (69) by dividing both numerator and denominator by their greatest common divisor, which is 3.y=(23)x+9Now we have the slope-intercept form of the equation, where the slope (m) is 23 and the y-intercept (b) is 9.
Determine Slope: Determine the slope of the line.From the equation y=23x+9, we can see that the slope of the line is 23. This means that for every 2 units the line moves horizontally to the right, it moves 3 units vertically upwards.
Determine Y-Intercept: Determine the y-intercept of the line. The y-intercept is the point where the line crosses the y-axis. From the equation, we can see that the y-intercept is 9. This means the line crosses the y-axis at the point (0,9).
Analyze Characteristics: Analyze the characteristics of the line.Based on the slope and y-intercept, we can say that the line is rising as it moves from left to right, and it crosses the y-axis at 9 units above the origin. The line does not have any x-intercept in the given equation, as it does not cross the x-axis.
