Answer:
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" the y-intercept.
Since the given line has a y-intercept at (0,-15), then:
The formula for calculate the slope is:
Knowing that the given line contains the points (0,-15) and (-4,-3), we can calculate the slope. This is:
Substituting values into , we get that the equation of the line in Slope-Intercept form is:
Sorry but I don't think that this question is right. If it is then please ignore.
Answer:
r = 7
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( where r is the radius )
x² + y² = 49 ← is in this form
with r² = 49 ⇒ r = = 7
