A y = 1/2x + 5 B y = 1/2x + 7 c y = 2x + 5 D y = y = 2x + 7

Step-by-step explanation:

y = mx + b (slope-intercept form of a line)

m is slope

b is y-intercept

The y-intercept of the line is (0, 5) or 5.

y = mx + 5

The slope of the line can be found through rise over run.

(1, 7) and (2, 9) are two points on the line.

m = (y2-y1)/(x2-x1)

m = (9 - 7)/(2 - 1)

m = 2/1 = 2

The slope of the line is 2.

y = 2x + 5

Hi! The equation for this line would be c), y = 2x + 5.

Step-by-step explanation:

Slope - intercept form: y = mx + b, where m is the slope and b is the y - intercept.

First, we should determine the y - intercept. We can observe using the graph that the line intercepts the y - axis at point (0, 5), so we take the y - coordinate (5) and insert it into our equation.

y = mx + 5

This automatically rules out options d) and b).

Next, we find the slope. The formula for finding the slope is (y2 - y1) ÷ (x2 - x1).

We need to choose two coordinates before we can calculate the slope.

Let's use (1, 7) and (0,5).

We will not insert the values into or slope formula:

(7 - 5) ÷ (1 - 0)

When we solve this, the quotient is 2.

This is our slope, and we can insert the value into our slope equation - -

y = 2x + 5

This rules out option a). So, your answer is option c), y = 2x + 5.

Hope this helps!

is there any photos or whatever?

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
