Answer: (5, -7)
Step-by-step explanation:
On a graph, the solution(s) of two equations is/are the points at which they intersect.
For the graph shown, there is only one intersection point, (5, -7). This set of coordinates satisfies both equations, so it is a solution to the system.

Answer:
the answers B c=35h+50
Step-by-step explanation:
Answer:
- gradient is 4.
- y-intercept is -5.
- No.
Step-by-step explanation:
1. In order to find the gradient of equation, you have to make it into slope-form equation y = mx + b :




So m represents gradient. In this question, m is 4.
2. Make it into slope-form equation :



In this question, y-intercept is b which is -5.
3. You have to substitute x-coodinate into the equation to see whether it is equal to y-coordinate :





Step-by-step explanation:
option number of b is write
