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>
Answer:
x= - 7 / 3
Step-by-step explanation:
1st determine the sign: -6=5x - 17 / -3
2nd move the terms: -6 = 5x + 17 / 3
3rd calculate:: -5x = 17 / 3 + 6
4th divide both sides: -5x = 35 / 3
Solution: x = - 7 / 3
Step-by-step explanation:
the first question
x-2/5=7
you need to use the same rules as pemdas but sorta in reverse. starting with multiplying 7 by 5, which is 35
x-2= 35
then you would add 2 to 35
making the answer x=37
You'd follow the same steps for the second one.
