Y=mx+b
slope= <u>rise
</u> run
<u />If its already graphed then you find where the line meets the y- line ( thats the b in the equation) from there you go up or down on the y- line to the point where the line next meets directly over another vertical line on the grid, the number of times you moved up or down is the "rise" in the equation for slope. After finding rise your move left or right from that point on the y-line until you meet the point where the line is and that will be the run. That fraction or number once you simplify the equation is you slope. Hope that helps.
The type of math is graphing and its super easy once u get it all you have to do is you have to get the top number (x) and the bottom number (y) and thats a coordinate pair so like the first one is 2,3 so just go right two and up three for secomd right 5 up 9 and so on
He left his house at 2:30 PM, because 45 minutes and 15 minutes is equal to one hour, and if he also spent 30 minutes walking to the mall, he spent an hour and 30 minutes to get to His mom's office. So he must have left at 2:30 PM to arrive at 3:00 PM
Answer:
Step-by-step explanation:
The interior angles of a heptagon add up to 5*180 = 900
So
x + 143 + 116 + 135 + 135 + 116 + 155 = 900 Add up the known angles
x + 800 = 900 Subtract 800 from both sides
x + 800 - 800 = 900 - 800 Combine
x = 100
