Answer:
the slope-intercept equation of a line that passes through the coordinate (-4,5) and (8,-1) is
Step-by-step explanation:
1) Apply the slope formula; y^2 - y^1 divided by x^2 - x^1
y^2 is -1
y^1 is 5
x^2 is 8
x^1 is -4
-1 - 5 = -6
8 - (-4) = 12
-6/12 is -1/2 or -0.5
2) To find the y-intercept, hoose either of the coordinates and replace y, m, and x in the y= mx+b formula.
5= -0.5(-4) + b
5= 2 + b
3= b
B would be the correct answer. If you take 4:13 in order to form a ratio equal to that you have to multiply both sides of the ratio by the same number. 4*4=16 and 13*4=52

Answer:
A . 17/21
B . 14/21
C . 7/14
D. 11/17
Step-by-step explanation:
So change from 50 to 35
first find change
50-35=15
50=100%
15=x%
percent means parts out of 100
15 out of 50=x/100
15/50=x/100
30/100=x/100
30=x
the answer is 30% change
