Question

WILL GIVE BRAINLIEST!!
Hi there, this lesson is way overdue and I really need to get it done. Can someone please help me figure them out?

1. Find the slope of the line that passes through (-2,-3) and (1,1).
A) 1/3
B) 1
C) 2
D) 4/3

2. A line with slope = 1/2 passes through the points (2,5) and (x,3). What is the value of x?
A) -1
B) 1
C) -2
D) 2

3. For the equation -4y =8x, what is the constant of variation?
A) -4
B) -2
C) 1
D) 2

Answer 1

1. is D) 4/3    To find the slope we will insert the numbers into this formula: y2 - y2 / x2 - x1, so... 1 + 3/ 1 + 2 (the negatives canceled each other out)

now simplify and it becomes 4/3

so ur answer to 1. is D) 4/3

2. Plot this one...it rly helps...then use the slope to find the point ur looking 4, the answer is C) -2

3. The answer is B) -2

Hope that helps u out!! :)
