Slope-intercept form: y = mx + b (m is the slope, b is the y-intercept or the y value when x = 0 -->  (0, y))

To find the slope(m), you can use the slope formula and plug in 2 points:

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

(x₁ , y₁) = (0, 2)

(x₂ , y₂) = (4, 5)

m = \frac{5-2}{4-0}

m = \frac{3}{4}

[slope is also m=\frac{rise}{run}  "rise" is the number of units you go up(+ number) or down(negative number). "run" is the number of units you go to the right. If your slope for example is 2, you go up 2 units and to the right 1 unit. If your slope is -2, you go down 2 units and to the right 1 unit.]

^ you could just look at the graph and see how many units a point goes up or down and to the right to get to the next point (goes up 3, to the right 4)

y=\frac{3}{4} x+b  To find b, plug in either of the 2 points into the equaation

(0,2)

2=\frac{3}{4}(0)+b

2 = b

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

Hey can anyone help find the missing measurement pls
Komok [63]

Answer:

? ≈ 6.5 yd

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = \frac{1}{2} bh ( b is the base and h the perpendicular height )

here A = 13.3 and h = 4.1 , then

\frac{1}{2} × 4.1b = 13.3 ( multiply both sides by 2 to clear the fraction )

4.1b = 26.6 ( divide both sides by 4.1 )

b = ? ≈ 6.5 yd ( to the nearest tenth )

Solve for W.<br><br> 4w-4+2(5w+8)=-2(w+3)<br><br> Simplify your answer as much as possible.
gayaneshka [121]

Answer:

w = -\frac{9}{8}

Step-by-step explanation:

The question is  4w-4+2(5w+8)=-2(w+3)

We can first use distributive property to simplify, the distributive property is  a(b+c)=ab+ac

Thus we have:

4w-4+2(5w+8)=-2(w+3)\\4w-4+10w+16=-2w-6

<em>Now we combine like terms and simplify to get the final answer for w</em><em>.</em>

4w-4+10w+16=-2w-6\\14w+12=-2w-6\\14w+2w=-6-12\\16w=-18\\w=\frac{-18}{16}\\w=-\frac{9}{8}

Thus, w = -\frac{9}{8}

What is the value of y?
Aleks04 [339]
To solve for the value of y, all you have to do is add up all the expressions and values together and make it equal to 180 degrees.

Y + (Y - 12) + 56 = 180
2Y - 12 + 56 = 180
2Y + 44 = 180
Y = 68 degrees.
