And let's calculate the value of b negative five times negative four that's positive twenty. So weMoreAnd let's calculate the value of b negative five times negative four that's positive twenty. So we have three is equal to twenty over three plus b.
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.
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.
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.

To find the slope using a general or standard form equation, use the slope formula: m=-A/B where A and B are integer variables found in the equation. The m is the slope.
The general form ax+by+c=0 is one of the many different forms you can write linear functions in. Other ones include the slope intercept form y=mx+b or slope-point form. We can convert the linear function among different forms.
So let's start by writing the equation in point slope form. So all we need to do is replace y1 withMoreSo let's start by writing the equation in point slope form. So all we need to do is replace y1 with positive five M with negative 2 and X1 with negative four.
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.
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.
