What is the equation of this line in slope-intercept form?

y=3x−1

y=−3x−1

y=−1/3x−1

y = 3x + 1

number graph ranging from negative six to six on the x and y axes. a line is drawn on the graph that passes through the labeled points begin ordered pair negative 1 comma 2 end ordered pair and begin ordered pair 1 comma negative 4 end ordered pair

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

600,000,000,000, or 6e14
