Answer:
Step-by-step explanation:
The form of equation of line given in the problem is the point-slope form of a line. That is given by:
We need 
and m (denoted by boxes)
is the y coordinate of the first set of points.
The first coordinate pair is (9,7), so would be 7
Now, the slope (m).
It has formula
So, x_1 = 9
y_1 = 7
x_2 = 4
y_2 = -8
Substituting, we get the slope to be:
Hence, the equation of the line in point-slope is:
Hey there!!
The area given : 25 square yards
We will find the length of the square.
Square area = side²
side² = 25
side = √25
side = 5 yards.
Now convert this into inches
1 yard --> 36 inches
5 yards --> 180 inches
Area = 180²
Area = 32400 inches²
Hope my answer helps!!
Morning temperature = −2°F
Afternoon temperature = +1°F
Night temperature = 0°F
Answer
The morning temperature was 2 degrees below the night temperature
-7x-5y=5
-(-9x-5y)=15 It's minus because negative times negative = positive
2x=-10
x= -5
-7(-5) - 5y = 5
35-5y =5
-5y = -30
y=6
Answer:
k = 13
Step-by-step explanation:
The sum of the angles is 180 since they form a straight line
4k-7 + 90 + 3k+6 = 180
Combine like terms
7k+89=180
Subtract 89 from each side
7k+89-89 = 180-89
7k =91
Divide each side by 7
7k/7 = 91/7
k = 13
