Need Help ASAP What is the equation of the line shown in the graph?

The equation of a line is y = mx + b where m is the slope and b is the y-intercept (the point where the line crosses the y-axis). we can look at the graph and see that the line crosses the y axis at y = 4. Therefore, the y-intercept, b, is 4.

Now we must calculate the slope. To do so, we divide the "rise" of the line,
y₂ - y₁ by the "run" of the line x₂ - x₁. We must choose two points (x₁, y₁) and (x₂, y₂) to find the slope. Two points are already given to us, (1, 2) and (4, -4):

m = (-4 - 2)/(4 - 1)

m = -6/3

m = -2

Now that we know the slope and the y-intercept, we can simply plug them back into the equation to find the equation of the line:

y = -2x + 4

Consider the inequality-5(x+7)<-10 write an inequality representing the solution for x
GrogVix [38]

Answer:

<h2>x > -5</h2>

Step-by-step explanation:

-5(x + 7) < -10            <em>use the distributive property </em><em>a(b + c) = ab + ac</em>

(-5)(x) + (-5)(7) < -10

-5x - 35 < -10         <em>add 35 to both sides</em>

-5x < 25         <em>change the signs</em>

5x > - 25       <em>divide both sides by 5</em>

x > -5

Samantha correctly answered 36 out of 48 questions on a test. She must score 70% or greater to pass the test. Did she pass?
lys-0071 [83]

Answer:

Yes

Step-by-step explanation:

You see that you need a percentage. You are given the amount that she got wrong, assuming the questions are weighted the same, you divide 36 by 48. This gives you .75. Then you multiply .75 by 100% giving you 75%.
