Answer:
hhhhjhgbbbjjhjjjjjkkkkkkkk
First, we find the equation of the line...
(1,3),(-3,7)
slope = (7 - 3) / (-3 - 1) = 4/-4 = -1
y = mx + b
slope(m) = -1
use either of ur points.... (1,3)...x = 1 and y = 3
now sub into the formula and find b, the y int
3 = -1(1) + b
3 = -1 + b
3 + 1 = b
4 = b
so the equation for this line is : y = -1x + 4 which is usually written as :
y = -x + 4
Now...to find where the line crosses the x axis (or the x intercept)...we sub in 0 for y and solve for x
y = -x + 4
0 = -x + 4
x = 4... so ur x intercept (where the line crosses the x axis) is : (4,0)
<u>Answer:</u>
The correct answer option is D. 5.
<u>Step-by-step explanation:</u>
We are given the following expression where 4 is to be divided by a fraction 1/5:
÷ 
This can also be written as:
Now to find the quotient of this, we will take the reciprocal of the fraction in the denominator to change it into multiplication.
Therefore, ignoring the 1 in denominator, we can simply multiply 4 by 5.
