Question

What is the point-slope form of an equation with the slope of 3/5 that passes through the point (10, –2)?

A. y + 2 = 3/5(x – 10)
B. y – 10 = 3/5(x + 2)
C. y + 10 = 3/5(x – 2)
D. y – 2 = 3/5(x + 10)

A line in the Cartesian plane passes through the points (–2, 4) and (2, –1). What are the rise and the run of the line?
A. The run is –5, the rise is 4.
B. The rise is –4, the run is –5.
C. The run is 4, the rise is 5.
D. The rise is –5, the run is 4.

If the slope of a line is 2 and its y-intercept is 5, what is the equation of the line?
A. y = 2x + 5
B. x = 5y + 2
C. y = 5x + 2
D. x = 2y + 5

17. What quadrant would the ordered pair (–4,–6) fall in?
A. IV
B. I
C. III
D. II


18. Using the point-slope formula, what is the equation of the line that passes through the points (1, 5) and (0, 0)?
A. y = 5x – 1
B. y = 5x
C. y = 5x + 10
D. y = x

Answer 1

Answer to the first question is A. X = 10 and y = -2. Plug it into the equation.
-2 + 2 = 3/5(10 - 10)
0 = 0

Answer to the second question is A. It is going up "rise" by 4. And left "run" by -5

Answer to the third question is A. 2x will represent the slope. 5 will represent the y intercept.

Answer to the fourth question is C.

Answer to the last question is B. y = 5(1) y = 5. y = 5(0) y = 0.

Hope that helps
