In general form they would be the same. So you can use whichever you prefer. So I'm going to say yMoreIn general form they would be the same. So you can use whichever you prefer. So I'm going to say y minus 6. Equals now my slope is up here negative eight over three times x minus X1 was 1..
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept). We can rewrite an equation in point-slope form to be in slope-intercept form y=mx+b, to highlight the same line's slope and y-intercept.
We can rewrite an equation in slope-intercept form (y=mx+b) to be in standard form (Ax+By=C) instead. In this example, we rewrite the slope-intercept equation y=2/3x+4/7 in standard form.
The standard form is represented in linear equations as Ax + By = C, where A, B, and C are constants. This form clearly lets us see the coefficients (the numbers multiplying x and y). For example, the equation 2x + 3y = 7 is in standard form.
How do I convert slope intercept form to standard form? Move all the terms to one side of the equality sign. Remember about changing the signs! Rearrange the equation so that the term with x is first, then the term with y , and then the intercept last. We now have mx - y + b = 0 and… this is already the standard form!
These are the two methods to finding the equation of a line when given a point and the slope: Substitution method = plug in the slope and the (x, y) point values into y = mx + b, then solve for b. Point-slope form = y − y 1 = m ( x − x 1 ) , where ( x 1 , y 1 ) is the point given and m is the slope given.
So anytime that you need to write an equation we always start out in point slope. Form. So pointMoreSo anytime that you need to write an equation we always start out in point slope. Form. So point slope. Form here's our X1 y1 we're going to do y. Minus that y1 which is 1 so y + 1 equals our slope.
So we have three is equal to twenty over three plus b. Now to solve for b it's helpful if we can getMoreSo we have three is equal to twenty over three plus b. Now to solve for b it's helpful if we can get rid of this fraction i'm gonna multiply everything by three.
Since we have a graph, we can find the slope using rise over run, 6 2 = 3 and the y-intercept is (0, 6). The equation of the line, in slope-intercept form, is y = 3 x + 6 . To change the equation to general (standard) form, subtract the x-term to move it over to the other side.
To derive the point slope formula, we consider a line of slope 'm' with a point (x1,y1) ( x 1 , y 1 ) . If (x, y) is any general point on the line, then the slope of the line is, m = (y - y1 1 )/(x - x1 1 . From this, we can get the point slope formula y − y1 1 = m (x − x1 1 ).
