Answer:
<h2>y = -x - 1</h2>
Step-by-step explanation:
From the graph we have:
y-intercept = -1
x-intercept = -1
The slope-intercept form of an equation of a line:
<em>y = mx + b</em>
m - slope
b - y-intercept
Therefore we have: <em>y = mx - 1</em>
Put the coordinates of the x-intercept to the equation:
(-1, 0) → x = -1 and y = 0:
0 = -1m - 1 <em>add m to both sides</em>
0 + m = -m + m - 1
m = -1
Finally we have the equation:
<em>y = -1x - 1</em>
Dang he's slow. If he's always at 5 MPH he's probably dead and riding an electric bike. By the way whats the question cuz you wrote
"Bob rode a bike at a constant rate of 5
mph."
Answer: 2
Step-by-step explanation:
Change the divisor 4.5 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.
We then have the equations:
90 ÷ 45 = 2
and therefore:
9 ÷ 4.5 = 2
Answer:
(x-9)²+(y-5)²=64
