Answer:
Slope = 
Step-by-step explanation:
The equation for finding slope is:
In the equation, m is the slope, x is the x-intercept, and b is the y-intercept. The number next to x is ALWAYS the slope.
Your equation:
The number(fraction) next to x is . Therefore, your answer will be
First find the slope
Slope formula: (y2-y1)/(x2-x1)
(-4-(-6))/(-2-2) = 2/-4 = -1/2
Slope intercept formula: y = mx + b
Y = -1/2x + b (solve for b)
Plug in any point
-6 = -1/2(2) + b
-6 = -1 + b, b = -5
Solution: y = -1/2x - 5
Answer:
A
Step-by-step explanation:
It would be B if it was asking the ratio of non-mammals to mammals.
Answer:
3/13
Step-by-step explanation:
There are 28 students. 1 studies biology but not art. 1 studies neither subject. Therefore, there are 26 students who study art.
Of the 26 students who study art, 6 also study biology. So the probability is 6/26, which reduces to 3/13.
