Answer:
the correct answer is number 2 and 3 and 4 just
The equation is y = mx + b
(18, -19)
substitute these numbers in the equation
-19 = 0(18) + b
-19 is y because it is the y slot in the cordinate and I put 0 for m because m is the slope and x is 18
-19 = 0 + b
b= -19
the equation is
y = 0(x) - 19
y = -19
Compare the linear function given with the slope-intercept form of a line, given by,
Where m is the slope and b is the y-intercept.
Comparing tells us that 10 is the slope. What does it mean?
<em>It means for </em><em>every unit increase in w (weeks)</em><em>, there is a </em><em>10 unit increase in number of laps</em><em>. </em>
This is choice 4.
ANSWER: "The number of laps Jessica increased her swim by each week"
Answer:
35% of the sixth grade is in the chess club
Step-by-step explanation:
if there are 100 students consider that as 100%
20 is a fifth of 100
20 x 5 =100
since 7/20 is a fraction you multiple the numerator (7) with the same number you multiplied to the denominator (20) which is 5.
7 x 5 = 35
35/100 = 35%
F(x) = 3x + 8
f(1) = 3 (1) + 8
f (1) = 3 + 8
f(1)= 11
