Write an equation of the line containing the given point and parallel to the given line. 3 -1 in parenthess 9x -7y 4 Simplify type in the from of ymx b. Thank?
This is simple algebra. You should know that parallel lines have the same slope. So you would take the slope of the line that is given to you and set it up in the equation y= mx + b. m stand for your slope and you would take the point that it gives you (3, -1) and plug it into y = mx + b (along with your slope) and solve for b..once you've solved for b, you can set up your equation because you know your slope (m) and y-intercept (b). If you are having trouble finding the slope, just solve the equation for y. Get y on one side of the equation. The number that is with x will be your slope. Good luck!
What is the equation of the line containing the points (0, 0), (-3, -9), and (9, 27)?
you should know this Find the difference of the y values over the difference in your x values to find the slope. Put it into the slope intercept form of the equation with one of the points substituted in and find the intercept. Rewrite the equation with the slope and the intercept. (-9-0)/(-3-0)=-9/-3=3 The slope. 27=3(9)+b 27=27+b 0=b Equation-> y=3x
How do you figure out slope in the equation y equals 12x 6?
This equation is in the slope-intercept form, y = mx + b, where the coefficient of x, m, is the slope and b is the y-intercept. Thus, in the equation y = 12x + 6, the slope is 12.
How do you find the right bisector of a triangle?
For triangle ABC, find the midpoint of side BC. Then, find the slope of side BC and use its negative reciprocal (since the negative reciprocal slope is the slope of the right bisector joining side BC and the opposite vertex). Finally, substitute the midpoint and negative reciprocal slope into the y=mx+b equation to get "b", then write the equation. :)
What is first step in graphing using slope intercept form of an equation?
Plot the y-axis, which is the b in the y=mx+b in the slope intercept equation. Then, you put your slope and plot the line.
