#of nickels :6
#of quarters:20
Step-by-step explanation:
- The slope and y-intercept of this line represented by the linear equation are 0 and -2 respectively.
- The linear relationship between the solutions (points) of the line values is that the points on the y-axis are constant while the points on the x-axis increased from left to right.
<h3>How to graph the line?</h3>
Mathematically, the standard form of the equation of a straight line is given by;
y = mx + c
Where:
In order to graph this line using the slope and y-intercept, we would have to express the given equation in the standard form as follows:
y + 2 = 0
y = -2
Therefore, the graph of the given equation is an horizontal line with y-intercept at -2
By critically observing the graph of the given equation, we can logically deduce that the linear relationship between the solutions (points) of the line values is that the points on the y-axis are constant while the points on the x-axis increased from left to right.
<h3>How to prove that the points are solutions of the linear equation?</h3>
Slope, m = Δy/Δx
Slope, m = (-2 + 2)/(6 - 2) = 0.
At point (2, -2), we have:
y = mx + c
y = 0(2) - 2
y = 0 - 2
y = -2 (Proved).
At point (6, -2), we have:
y = mx + c
y = 0(6) - 2
y = 0 - 2
y = -2 (Proved).

#SPJ1
Answer:
a = 3, b = -1
Step-by-step explanation:
a = 5b + 8
a = -10b - 7
5b + 8 = -10b - 7
Add 10b from both sides;
15b + 8 = -7
Subtract 8 from both sides;
15b = -15
Divide both sides by 15;
b = -1
Lets substitute b;
a = 5b + 8
a = 5(-1) + 8
a = -5 + 8
a = 3
ANSWER: 28
EXPLANATION:
Area is l • w or length • width. We know the width is 7 but for the length you only multiply the straight line. As 5 is slanted we use 4 instead, leaving us to multiply 7 • 4. This give us a solution of 28.
