The linear equation that has a slope of -7 and crosses the x-axis at (3, 0) is:
y = -7x + 21
<h3>
How to find the linear equation?</h3>
A general linear equation is:
y = a*x +b
Where a is the slope and b is the y-intercept.
The slope must be equal to the limit found in part a, and you say that it is equal to -7, so the slope is -7. And for how is written the problem, I understand that it crosses the x-axis at x = 3.
Then we will have:
y = -7*x + b
Such that, when x = 3, y = 0, then:
0 = -7*3 + b
21 = b
Then the linear equation is y = -7x + 21

Answer:
How far does Clare travel in one hour?
A: 36
How far does Clare travel in three hours?
A: 108
How far does Clare travel in 3.5 hours?
A: 126
Step-by-step explanation:
Find the Unit Value
72/2 = 36
Clare travels 36 miles per hour
Therefore, you must multiply the hours by the Unit travel time for the answers.
1 X 36 = 36
3 X 36 = 108
3.5 X 36 = 126
First get y by its self , then graph , find intersection point and plug in x and y to both equations, see if it makes sense , then the solution must be you intersection point
Answer:
No. Reduce 10/8 by dividing by 2. 10/8= 5, 8/2= 4. 10/8= 5/4. Reduce 16/20 by dividing by 4. 16/4= 4 , 20/4= 5. 16/20= 4/5.
