Answer:
the range of the relation is 3
Step-by-step explanation:
The point-slope form of an equation of a line:

m - slope
We ahve the slope m = 1/2 and the point (-2, 1). Substitute:

- point-slope form
Covert to the slope-intercept form (y = mx + b):
<em>use the distributive property</em>
<em>add 1 to both sides</em>
- slope-intercept form
Convert to the standard form (Ax + By = C):
<em>multiply both sides by 2</em>
<em>subtract x from both sides</em>
<em>change the signs</em>
- standard form
Convert to the general form (Ax+By+C=0):
<em>add 4 to both sides</em>
- general form
Y-intercept 168
x-intercept (-21)
If he saves $6 from every $15 he gets, then getting $75 means he saves $30.
Lets says he is paid 15 dollars every hour, and from those he saved 6 dollars. If he earned 72 dollars, that means he is paid 5 times (because 75/15 is 5). So if every time he is paid he saves $6, being paid 5 times means he saves $30 ($6 *5).
Answer:
The equation is y=-3x-2
Step-by-step explanation:
The first we need to know is the equation of a line, and it is y=mx+b
where the m is the slope and b is the interception to the y axis
With the information in the question the slope is -3 and the equation thats equal to m. and the y intercept of -2 thats equal to the b value
then y=-3x-2
