Any line can be graphed using two points. Select two x x values, and plug them into the equation to find the corresponding y y values. Tap for more steps... Graph the line using the slope and the y-intercept, or the points.

2020年11月8日 · To graph the equation y = 4x - 9, identify points by substituting values for x. The points (0, -9) and (1, -5) can be plotted and then connected with a straight line that has a slope of 4 and intersects the y-axis at -9.

2018年1月10日 · See a solution process below: First, solve for two points which solve the equation and plot these points: First Point: For x = 0 y = (4 xx 0) - 9 y = 0 - 9 y = -9 or (0, -9) Second Point: For x = 2 y = (4 xx 2) - 9 y = 8 - 9 y = -1 or (2, -1) We can next plot the two points on the coordinate plane: graph{(x^2+(y+9)^2-0.125)((x-2)^2+(y+1)^2-0. ...

the y-intercept is -9. That means when x=0, y=-9. the slope is 4. That means the line goes right 1 unit and up 4 units.

Axis interception points of 4 x − 9: X Intercepts: (4 9 , 0), Y Intercepts: (0, − 9)
