Answer:
y = 2x +1
Step-by-step explanation:
y=kx+1
Substitute the point into the equation
3 = k(1) + 1
3 = k+1
Subtract 1 from each side
3-1 = k
2 = k
y = 2x +1
The slope is 2 and the y intercept is 1
Answer:

Step-by-step explanation:
The correct answer would be B) $70+(-$9)+(-$7) because a negative plus a positive cancels out to make a negative, so even though there is a plus and a minus sign it really only means minus. Therefore, you solve it just like a simple math problem $70-$9-$7. In the end Betty ends up with $54 in total having spend $16.
