Plz help don’t understand

Answer:

Step-by-step explanation:

every time x goes up 1, y goes up 4

x = 3 minus x = 2 is a delta (a change of 1)

x = 4 minus x = 3 is a delta (a change of 1)

x = 5 minus x = 4 is a delta (a change of 1)

the delta x is ALWAYS 1 for this table you can always substract x's to find the delta delta is symbolized by Δ Δx for the delta x

y = 7 minus y = 3 is a delta (a change of 4)

y = 11 minus y = 7 is a delta (a change of 4)

y = 15 minus y = 11 is a delta (a change of 4)

the delta y is ALWAYS 4 for this table you can always substract y's to find the delta delta is symbolized by Δ Δy for the delta y

the slope m = Δy / Δx m = 4 / 1 m = 4

y = mx + b when x = 0 then y = b (called the y intercept)

so how do we find the y intercept?

look at the pattern in the TABLE Δx and Δy

when x = 1 y = (3 - 4) = -1

x = 0 y =( -1 - 4) = -5

so y = 4x - 5 is a line equation for the data in this table

I believe there are other forms for linear equations

I chose the y-intercept form

use the point slope equation

(y - y1) = m(x - x1) where (x1, y1) are the coordinates of a point on

the line

when you know the slope of the line and a point on the line

as before

m = (y2 - y1) / (x2 - x1) from the table

= (7 - 3) / (3 - 2) still equals

= 4/1 = 4

pick a point on the line say x= 4 and y = 11 (4, 11)

(y - y1) = m(x - x1)

y - 11 = 4(x - 4) point slope form

solving point slope form for y

y - 11 = 4x - 16 add 11 to both sides

y = 4x - 5 back to the y-intercept form

Answer:

Q/ Draw a line ; Ans; 

$\frac{9}{5} —>1 \frac{4}{5}$

*explain ; We put the 5 in the denominator and 5 multiply 1 + 4 so equal 9 so the choice 9/5 .

Ans; 7/3—> 2 1/3

*explain ; We put the 3 in the denominator and 3 multiply 2 + 1 so equal 7 so the choice 7/3 .

Ans; 12/10 —> 1 1/5

*explain; simple (12 and 10) ÷ 2 so equal 6/5

We put the 5 in the denominator and 5 multiply 1 + 1 so equal 6 so the choice 6/5 =12/10 .

$\frac{12 \div 2}{10 \div 2} = \frac{6}{5} = 1 \frac{1}{5}$

Q/ Compare the fractions;Ans;

$\frac{2}{3} < \frac{14}{6}$

* explain; 2/3 = 0.66 and 14/6=2.33 so 2.33 greater from 0.66 so 14/6 greater from 2/3 .

$\frac{3}{8} < \frac{8}{3}$

* explain; 3/8 = 0.375 and 8/3=2.666 so 2.666 greater from 0.375 so 8/3 greater from 3/8 .

$2 \frac{1}{6} > \frac{5}{9}$

* explain; 2 1/6 —> We put the 6 in the denominator and 6 multiply 2 + 1 so equal 13 so equal 13/6

13/6 = 2.16 and 5/9=0.55 so 2.16 greater from 0.55 so 13/6 = 2 1/6 greater from 5/9 .

Q/Add; Ans;

$\frac{7}{8} + \frac{5}{8} = \frac{7 + 5}{8} = \frac{12}{8} = \frac{3}{2}$

$\frac{1}{9} + \frac{2}{3} \\ \\ \frac{1}{9} + \frac{6}{9} = \frac{ 1+6 }{9} = \frac{7}{9}$

Q/Subtract; Ans;

$\frac{6}{7} - \frac{4}{7} = \frac{6 - 4}{7} = \frac{2}{7}$

$\frac{7}{3} - \frac{2}{9} \\ \\ \frac{21}{9} - \frac{2}{9} = \frac{21 - 2}{9} = \frac{19}{9}$

Q/ Multiply;Ans;

$\frac{1}{5} \times \frac{1}{2} = \frac{1}{10}$

$\frac{2}{3} \times \frac{3}{8} = \frac{6}{24} = \frac{1}{4}$

Q/Divide;Ans;

$\frac{3}{4} \div \frac{2}{5} \\ \\ \frac{3}{4} \times \frac{5}{2} = \frac{15}{8}$

$\frac{8}{9} \div \frac{1}{3} \\ \\ \frac{8}{9} \times \frac{3}{1} = \frac{24}{9} = \frac{8}{3}$

I hope I helped you^_^
