Answer:
Slope: -3, apparent point: (-1, -2)
Step-by-step explanation:
Point-slope form means the equation of a line is given in the form of y - y1 = m(x - x1), where x1 and y1 are coordinates of a point that lies on the line and m is its slope. Keeping this in mind while looking at the given equation, you can see that -3 is where m goes, meaning the slope is -3. You can also see that 1 and 2 are in the places where - x1 and - y1 go (don't forget those minus signs!) so you take those two and make them an ordered pair for your apparent point of (-1, -2).
Answer:
Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values. The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.

Answer:
he had $90
he bought a phone for $75
90-75=15
he has $15 now
15÷0.06=1500÷6=250 minutes
Answer:
y = 1/3x + 10/3
Step-by-step explanation:
→ Write gradient into format
y = 1/3x + c
→ Substitute in (5,5)
5 = 5/3 + c
→ Find c
c = 5 - 5/3 = 10/3
→ Finish off
y = 1/3x + 10/3
