3/4 is equal to 75%, or if you were going by .25=1/4 than it would be .75
A negative slope can be illustrated when a line that is trending downward from left to right, has a negative value.
<h3>What is a negative slope</h3>
It should be noted that a negative slope implies that two variables are negatively related.
This implies that when x increases, y decreases, and also when x decreases, y increases.
Graphically, a negative slope implies that as the line on the line graph moves from left to right, the line will fall.

Z = (score - mean)/sd
-1.75 = (x - 38)/4
Multiply both sides by 4:
-7 = x -38
Add 38 to both sides:
x = 31
He scored a 31 points on the exam
Answer:
(2, -4)
Step-by-step explanation:
1/2 x + 3/4 y = -2
2/3 x + 5/6 y = -2
4 (1/2 x + 3/4 y = -2 ) = -2(2x + 3y = -8) Multiply by -2 to eliminate the x's
6 (2/3 x + 5/6 y = -2) = (4x + 5y = -12)
<u> -4x - 6y = 16 </u> combine with the 2nd equation
-1y = 4
y = -4
plug -4 in for y to find x in either equation
1/2x + 3/4 (-4) =-2
1/2x - 3 = -2
1/2x = 1
x = 2
