Which equation represents the linear function that is shown on the graph below?

d1i1m1o1n [39]

Answer:

$y = \frac{1}{2}x - 2$

Step-by-step explanation:

Given

The attached graph

Required

Determine the linear equation

First, we need to calculate the slope

$m = \frac{y_2-y_1}{x_2-x_1}$

From the graph, the following relationships exist:

$(x_1,y_1) = (4,0)$

$(x_2,y_2) = (10,3)$

So, the expression for calculating slope becomes:

$m = \frac{y_2-y_1}{x_2-x_1}$

$m = \frac{3-0}{10-4}$

$m = \frac{3}{6}$

$m = \frac{1}{2}$

Next, we calculate the equation using:

$y - y_2 = m(x - x_2)$

This gives:

$y - 3 = \frac{1}{2}(x - 10)$

Open bracket

$y - 3 = \frac{1}{2}x - 5$

Make y the subject:

$y = \frac{1}{2}x - 5+3$

$y = \frac{1}{2}x - 2$

Write the sentence as an equation.

Answer:

35q-384 = 225q-189

Step-by-step explanation:

since its 384 subtracted from 35 times q it will be 35q-384 and then it says "is" which is an equal sign (=) and then q times 225 which is 225q decreased by 189 which is 225q-189 so it will be 35q-384 = 225q-189

Yuri [45]

Answer:

-50 <= -3

Step-by-step explanation:

2z + 2 - 4z - 16 <= 2z + 10

-2z - 14 <= 2z + 10

-4z - 14 <= 10

-4z <= 24

-z <= 6

z <= -6

2(-6+1)-4(-6-4) <= 2(-6 +5)

-10 -40 <= -3

-50 <= -3
