Answer:
Step-by-step explanation:
To find the slope, use 2 coordinates from your table and plug them into the slope equation, which is
Let's use the first 2 coordinates (-1, -2) and (0, -4). Plugging into the slope formula:
Therefore, we know that the slope is -2.
The y-intercept exists where x = 0. We see from our table that when x = 0, y = -4. So the y-intercept is -4.
To write our equation, we will use the slope-intercept form of a line, which is
y = mx + b, where m is the slope and b is the y-intercept. Plugging in both our values for slope and the y-intercept:
y = -2x - 4
Answer:
They bought 3 hot dogs and 5 drinks
Step-by-step explanation:
Well, its mostly guess and check.
x=hot dogs y= drinks x+y=8
2x + 1y =11
2(1) + 1(7) = 9 (wrong answer)
2(2) + 1(6)= 10 (wrong answer)
2(3) + 1(5) = 11 (right answer)
The reason I pick these numbers is because the x and the y need to add up to 8 and as you can see on each try they added up to 8 but it also had the equation itself had to add up to $11. So, you substitute the numbers that add up to 8 to x and y to make sure the equation equals 11.
Answer:
To find the perimeter of the triangle, you would add p + m + n. To find the area of the triangle you would use (p x m) /2. To find a missing side of the triangle, given that it is a right triangle, you would use p^2 + m^2 = n^2
