Answer:
a = 8
b ≠ 18
Step-by-step explanation:
y = 4x - 7
2y = ax + b
For there to be no solution, the lines (if graphed) should be parallel meaning that their slopes are equal but the y-intercepts are different
y = mx +b is the equation of a line where m is the slope and b is the y-intercept
Multiply the first equation by 2
2y = 8x - 14
2y = ax + b
So a has to equal 8
b can be anything except 14 (otherwise the lines would be the same)
You express the values in which the teacher or tutor or whatever assigned you.

Answer:
3
Step-by-step explanation:
I think it’s positive. As it gets heavier, the cost has a positive slope, or increases. I’m not absolutely sure though
