Answer:
<h2>y = -2x - 10</h2>
Step-by-step explanation:
The formula of a slope:
We have two points (-5, 0) and (-1, -8). Substitute:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercpet
Put the value of the slope and coordinates of the point (-5, 0) to the equation of a line:
<em>subtract 10 from both sides</em>
Finally:
4 is the answer
Divide by negative 5 on the right
Subtract 3y and move it to the right
X= 1 - 3Y
To solve this, you need to isolate/get the variable "u" by itself in the inequality: u = unknown number
2u - 3 < 1 Add 3 on both sides
2u - 3 + 3 < 1 + 3
2u < 4 Divide 2 on both sides to get "u" by itself
u < 2 (u is any number less than 2)
When the inequality sign is >/< (greater than/less than), the dot/endpoint is an open/unfilled circle.
When the inequality sign is ≥/≤ (greater than or equal to/less than or equal to), the dot is a closed/filled circle.
u < 2
Start making a ray by placing an open circle on 2(click on the dot/endpoint to change it to be open if it isn't already), then have the ray point left where the numbers would be decreasing because "u" is any number less than 2. If you can place the end of the ray at the end of the number line.
