Answer:
y=2x-3
Step-by-step explanation:
1. find the slope
6x-3y=21
-3y=-6x+21 divide both sides by -3
y=2x-7
slope is 2
2.y-5=2(x-4)
y-5=2x-8
y=2x-8+5
y=2x-3
PARALLEL lines have the same slope
Answer:
y = -2x + 1
Step-by-step explanation:
Then any equation of the form y = -2x + b, b≠1 will create a system with no solution. Hence the values of m and b are m = -2, b ≠ 1.

Answer: 9
Step-by-step explanation:
4x²-7x+7 f(2)=4*(2)^2-7(2)+7=16-14+7=9
Step-by-step explanation:
each point should be at a 2. the center is 0,0
Answer:
The inequality
have a dashed line
Step-by-step explanation:
we have
![5x-3y >15](https://tex.z-dn.net/?f=5x-3y%20%3E15)
The solution of this inequality is the shaded area below the dashed line
The equation of the dashed line is ![5x-3y=15](https://tex.z-dn.net/?f=5x-3y%3D15)
The slope of the dashed line is positive
The y-intercept of the dashed line is -5 ---> point (0,-5)
The x-intercept of the dashed line is x=3 ----> point (3,0)
Graph the solution
