60 students on field trip 20 students were 8th graders. What ratio shows relationship between eighth graders and everyone who we
Flauer [41]

Answer:

Percentage=33.33%

Step-by-step explanation:

Total number of students=Number of 8th grader+others who went on trip

where;

Total number of students=60

Number of 8th graders=20

Others who went on trip=x

replacing;

60=20+x

x=(60-20)

x=40

Others who went on trip=x=40

Ratio of number of eighth graders to the number of everyone who went on the trip is;

Eighth graders who went=20 students

Everyone who went including the eighth graders=60

20/60==1/3

(1/3)×100=33.33%

Percentage=33.33%

Point slope graph y+2÷4(x+5)
ladessa [460]

Answer:

See attachment for graph

Or

The slope intercept form is y=4x+18

Step-by-step explanation:

Assuming you want to graph the straight line given in point-slope form as

y+2=4(x+5)

Then we need at least two points on this line

When we compare to the point-slope formula y-y_1=m(x-x_1) then we  obtain (-5,-2) as a point on this line so we plot it.

When x=0, y=4(0+5)-2=18 so we plot (0,18)

We then draw a straight line through as shown in the attachment.

On the other hand, if you had wanted the equation slope intercept form, then we expand to obtain:

y+2=4x+20

\implies y=4x+20-2

\implies y=4x+18
