Describe two different methods you can use to graph the equation y=2x+4.

1 answer:

4 0

One way is the 4 is the Y- intercept so you could graph that and the 2 is the slope so you would go up 2 units right 1 unit up 2 units right 1 unit ect.

Another method would be to plug in 0 for X and get the Y intercept then plug in 0 for Y and find the X intercept. graph the points and connect

Which linear function represents the line given by the point-slope equation y + 7 = –y plus 7 equals negative StartFraction 2 Ov

Citrus2011 [14]

Answer:

Negative Start Fraction 2 Over 3 End Fraction x minus 11

$f(x)=-\frac{2}{3}x-11$

Step-by-step explanation:

we have

$y+7=-\frac{2}{3}(x+6)$

Convert to slope intercept form

$y=mx+b$

Solve for y

That means -----> Isolate the variable y

Distribute in the right side

$y+7=-\frac{2}{3}x-\frac{2}{3}(6)$

$y+7=-\frac{2}{3}x-4$

subtract 7 both sides

$y=-\frac{2}{3}x-4-7$

$y=-\frac{2}{3}x-11$

Convert to function notation

Let

f(x)=y

$f(x)=-\frac{2}{3}x-11$

therefore

The linear function is

Negative Start Fraction 2 Over 3 End Fraction x minus 11

Answer:

4. 28 sq. inch

Step-by-step explanation:

First, Area of the square = l² = 2² = 4

Area of the triangle = 1/2 x b x h

= 1/2 x 2 x 6

= 6

Total surface area = Area of square + 4 x area of triangle

= 4 + 4 x 6

= 28
