y=3x+1
Use the slope-intercept form to find the slope and y-intercept
The slope-intercept form is y=mx+b
, where m is the slope and b
is the y-intercept.
y=mx+b
Find the values of m
and b using the form y=mx+b
.
m=3
b=1
The slope of the line is the value of m
, and the y-intercept is the value of b
.
Slope: 3
Y-Intercept: 1
Any line can be graphed using two points. Select two x
values, and plug them into the equation to find the corresponding y
values.
Choose 0
to substitute in for x
to find the ordered pair.
Replace the variable x
with 0
in the expression.
f(0)=3(0)+1
Simplify the result.

Replace the variable x
with 1
in the expression.
f(1)=3(1)+1
Simplify the result.
Multiply 3

Answer:
f(x) has a slope of -1 and has a range of all real numbers.
Step-by-step explanation:
A linear function is a continuous function, so that exist a range value for all value of the domain, which corresponds to all real numbers. Regarding the function described above, the y- and x-intercepts are, respectively:
x-Intercept
f(x) has a x-intercept of (-24,0).
y-Intercept
f(x) has a y-intercept of (0, -24).
Lastly, the linear function has a slope of -1.
Answer:
6 matches
Step-by-step explanation:
Let’s call the teams A B C D
A will play B C D = 3 matches
B will play only C and D as it already played A, making 2 matches
C will play D, making 1 match
D has already played all
Total number of matches is thus 3 + 2 + 1 = 6 matches
Molly's equation
15x + 10 = 100
-10 -10
15x=90
/15 /15
x=6
Maddie's equation
15x - 10 = 100
+10 +10
15x=110

give the guy under me the 5 stare and a thanks this is his answer
Answer:
-1/2
Step-by-step explanation:
the slope is difference in y over difference in x, so (-3-(-1))/(2-(-2)): aka -2/4 aka -0.5 or -1/2
plug in the points to find the y intercept,
the equation of the line is y = -0.5x -2 incase you need it.
