Answer:
m=1/2 b =6
Step-by-step explanation:
m is the the gradient ( as in how much that line slant), so just use the formula
y2 - y1
------------
X2 - x1
For b, that the y-intercept,
Once u found m
Just choose any one of the coordinate they gave u (4,8) or(-6,3)
It will give u the same answers
Let's say u chose (4,8)
Theredore x = 4, y =8
y=mx + b
8= 1/2 x 4 + b
b= 6
The other one would give u the same answer
The most likely answer is 5/6
Answer:
y=1/2x-7
Step-by-step explanation:
Answer:
Part A:
x+y= 95
x = y+25
Part B : 35 minutes
Part C : No
Step-by-step explanation:
Eric plays basketball and volleyball for a total of 95 minutes every day
x+y= 95
Where:
x =the number of minutes Eric plays basketball
y= the number of minutes he plays volleyball
He plays basketball for 25 minutes longer than he plays volleyball.
x = y+25
System:
x+y= 95
x = y+25
Replacing x=y+25 on the first equation:
(y+25) + y =95
Solving for Y
y+25+y =95
25+2y=95
2y=95-25
2y=70
y = 70/2
y = 35 minutes
Part C : No
if x = 35
x+y= 95
35+y =95
y= 95-35
y = 60 minutes
Replacing y=60 on the other equation:
x = y+25
35 = 60+25
35 ≠85
