Answer <u>(assuming it can be in slope-intercept form)</u>:

y = \frac{3}{4} x+2

Step-by-step explanation:

When knowing the y-intercept and a slope of a line, you can write its equation in slope-intercept form, or y = mx + b format.  

1) First, find the slope. Use two points from the graph. We can see that the points (0,2) and (4,5) are on the line, therefore substitute their x and y values into the slope formula m = \frac{y_2-y_1}{x_2-x_1} and solve:

m = \frac{(5)-(2)}{(4)-(0)} \\m = \frac{5-2}{4-0} \\m = \frac{3}{4}

Thus, the slope is \frac{3}{4}.

2) Next, find the y-intercept of the line by looking at the graph. The y-intercept is the point at which the line intersects the y-axis. By reading the graph, we can see that that point is (0,2), thus 2 is the y-intercept.

3) Now, using the slope-intercept formula y = mx + b, substitute the found values for the m  and the b to write the equation of the line.

Since m represents the slope, substitute \frac{3}{4} in its place. Since b represents the y-intercept, substitute 2 in its place. This gives the following answer and equation:

y = \frac{3}{4} x+2

Paloma ran 3 3/4 miles around the school track. If each lap is 1/2 mile, how many laps did she run?
Ratling [72]

Answer:

9

Step-by-step explanation:

It is 9 because 1/2 goes into 3, 6 times, and then 3/4 divided by 1/2 is 1 1/2 so 1/2 goes into 3/4 1/12 times, so then figure out how mnay 1/2 is in 1 1/2 and youll get 3 so 6 plus 3 equals 9 :)

Find the area of an equilateral triangle (regular 3 Gon) with the given measurement 9 in perimeter a=SQ.in
blsea [12.9K]

Answer:

3.897 in^{2}

Step-by-step explanation:

equilateral triangles are also equiangular, meaning the have equal angles.

Triangle sum theory says that angles of a triangle add up to 180.

That means each angle is 60.

A = bh/2

You need the (h). The base of is 3.  Perimeter = 9, so each side is 3

Draw a perpendicular line for the height. The line cuts the base in half (1.5)

Using trigonometry you can find the height.

tan 60° = h/1.5

h = height, 1.5 is half of 3, 60° is the base angle.

multiply each side by 1.5

1.5(tan 60°) = h

h=2.598

then substitute h into formula

A= <u>(2.598)(3) </u>

           2

A = 3.897 rounded

Write an equation of a line that is parallel to the line whose equation is 3y=x+6 and that passes through the point (-3,4).
Monica [59]
The standard form of this equation is

y=\frac{1}{3}x+2

The slope of two parallel lines i the same, so the slope of the line we're looking for is also \frac{1}{3}

Since the line passes through (-3,4), the equation is:

(y-4)=\frac{1}{3}(x+3)

\boxed{y=\frac{1}{3}x+5}
