Answer:
The equation of the line would be A) y - 8 = -2(x + 2)
Step-by-step explanation:
In order to find the equation of the line, we need to start by finding the slope. We can do that with the slope equation.
m(slope) = (y2 - y1)/(x2 - x1)
m = (-2 - 8)/(3 - -2)
m = -10/5
m = -2
Now that we have the slope at -2, we can plus in the first point into point-slope form and find the equation.
y - y1 = m(x - x1)
y - 8 = -2(x + 2)
<u>QUESTION 2</u>
Answer:
The correct answer is B) x-intercept = -4 and y-intercept = -3
Step-by-step explanation:
We can tell this because the y-intercept is the value of y when x = 0. So we put 0 into x for the equation.
3x + 4y = -12
3(0) + 4y = -14
4y = -12
y = -3
Since B is the only answer with an y-intercept at -3, we know it to be the correct answer.
Answer:
bottom: 12 x 12 = 144
1st triangle: (12 x 8)/2 = 48
2nd triangle: 48
3rd triangle: 48
4th triangle: 48
144 + 48 + 48 + 48 + 48 = <u>336 cm squared</u>
