First, we must understand what standard form of a line is. Standard form of a line is written like such that A,B, and C are all integers, and A must be positive. First, we must calculate the slope of the line that passes through theses coordinates.
<span>As a refresher, this is the equation to figure out the slope of two coordinates.Now, we just simplify the numerator and denominator. <span> </span></span>
The next step is to utilize point-slope form, which is where is a point on the line. Of course, we already know that (7,-3) and (4,-8) both lie of the line. Therefore, plug in one fot he coordinates. Once converted into point-slope, we must then convert into standard form. This is what is demonstrated in the next step.
<span>Let's multiply all sides by 3 to get rid of the fraction early.Distribute the 5 to both terms in the parentheses.Subtract 9 from both sides.Subtract 5x on both sides.We aren't done yet! The coefficient of the x-term must be positive. Therefore, divide by -1 on both sides.<span>This is standard form now, so we are done!</span></span>
A 42 24÷16 =1.5 1.5×28 =42 b i think its 78.4 im not sure
Price in the sale=£31-10% of £31
price in the sale=£31-(10/100)*£31=£31-(10*£31)/100=£31-£3.1=£27.9
The price in the sale is £27.9
