Equation of a line is given by y = mx + c; where m is the slope and c, the y-intercept.
Therefore for line y = 12x + 7, the slope is 12
Step-by-step explanation:
9x - 2 = 5x + 54 because these angles are corresponding
9x - 5x = 54 + 2 add/subtract like terms
4x = 56 and this divided by 4
x = 14
9x - 2 + 10y + 6 = 180° because these two angles makes a straight line
9×14 - 2 + 10y + 6 = 180°
126 - 2 + 10y + 6 = 180° add like terms
130 + 10y = 180° subtract 130 from both sides
10y = 50 divide by 10
y = 10
Answer: Our required interval for temperature is 
Step-by-step explanation:
Since we have given that
The normal temperature range for Yuma, on Janurary is atleast = 48 degrees
and the highest temperature on that day is no higher than 64 degrees.
Let the temperature in Yuma be 'x'.
So, we know that for atleast means it can 48 degrees or more, and no higher than means it should be equa to or less than 64 degrees.
Mathematically, it is expressed as

Hence, our required interval for temperature is
