Answer:
i think it is A
Step-by-step explanation:
i hope this helped!
p.s it would be cool if you gave me brainliest.
Slope intercept form isy=mx+b
m=slope
b=y intercept
ok so to find the slope when given 2 points you do
slope=(y1-y2)/(x1-x2)
(x,y)
(-1,-9)
(2,6)
x1=-1
y1=-9
x2=2
y2=6
subsitute
slope=(-9-6)/(-1-2)
slope=(-13)/(-3)
slope=13/3
y=13/3x+b
subsitute a given point to find b
(2,6)
x=2
y=6
6=13/3(2)+b
6=26/3+b
subtract 26/3 from both sides
6-26/3=b
6=18/3
18/3-26/3=8/3
8/3=b
the equation si
y=(13/3)x+8/3
Answer:
the answer is D
how to try the values of the x and y
(x,y)
Answer:
√74
Step-by-step explanation:
there is no y.
wx=<8-3,-3+3,-6-1>=<5,0,-7>
|wx|=√(5²+0²+(-7)²)=√(25+49)=√74
Answer and Step-by-step explanation:
The answer is the second answer choice. y = 2x + 1
By looking at the graph, we see that there is a y-intercept at (0, 1), and it has a positive slope of 2.
