Find the equation of the line

y = -1/4 x + 2

Step-by-step explanation:

use y=mx+b

keep the x and the y

m is the slope

to find the slope put the rise (change in y between any two points that the line crosses) over the run (change in x between any two points that the line crosses) like this

rise/run

in this case the two points that I chose were (0, 2) and (4, 1), so fhe rise between them is -1, and the run between them is 4, so put -1/4 instead of your m in the equation

b is the y intercept

the y intercept is where on the y axis does the line cross the 0 x axis

basically just ask yourself, what is the y when the x is 0

in this case the line is crossing 2 y when it crosses the 0 x axis

So when the x is 0, the y is 2, so put the 2 instead of your b in the equation

the whole equation should be y= -1/4 x + 2

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
