Answer:
The slope of the line given by the linear equation is -2
The slope of the line shown in the graph is -1
Step-by-step explanation:
The line equation, y = -2x + 7 is written in the slope-intercept form, which is represented by the formula, y = mx + b.
m is the slope, while b is the y-intercept.
Therefore, the slope of the line of the linear equation, y = -2x + 7 is -2.
Find the slope of the line shown in the graph using the formula, 
.
Use the coordinates of any two points on the line. Let's use (0, 5) and (5, 0)
Let,
Therefore:
The slope of the line given by the linear equation is -2
The slope of the line shown in the graph is -1
<span>The area of the square is expressed in the formula A=s^2 where s is the length of the square. A square has four equal lengths. In this case, we are given with an area of 200 feet. The side then is the square root of 200 equal to 14.14 feet.</span>
Answer:
x=10, y=-1
Step-by-step explanation:
The coefficients of y are opposites, so the y-variable can be eliminated by adding the two equations.
... (x -y) +(2x +y) = (11) +(19)
... 3x = 30 . . . . . simplify
... x = 10 . . . . . . .divide by the coefficient of x
Use either equation to find y. We can use the first one, for example:
... 10 -y = 11
... -1 = y . . . . . add y-11
The solution is (x, y) = (10, -1).
His average is 80%. You take the two scores add them up and divide by the number of scores.
