The linear equation that represents the point (-2,3) and 3 more points with a slope of -1/2 is y = -1/2x + 2
<h3>How to graph the point (-2,3) and 3 more points using a slope of -1/2?</h3>
The given parameters are
Slope, m = -1/2
Point, (x1, y1) = (-2, 3)
The linear equation is calculated as:
y = m(x - x1) + y1
Substitute the known values in the above equation
y = -1/2(x + 2) + 3
Expand
y = -1/2x - 1 + 3
Evaluate the sum
y = -1/2x + 2
This means that the linear equation that represents the point (-2,3) and 3 more points with a slope of -1/2 is y = -1/2x + 2
See attachment for the graph of the point and the three other points

Answer: Chris reached Boston at 10:24 a.m.
Explanation:
Since we have given that
Speed at which Chris ran from Newton to Boston = 15 km/h
Speed at which Goffy ran from Newton to Boston = 12 km/h
Time at which both started = 10:00 a.m.
Time at which Goffy reached Boston = 10:30 a.m.
That means Goffy takes half an hour to reach Boston,
so, Distance between Newton and Boston is given by
So, Time taken by Chris to ran from Newton and Boston is given by
So, Chris reached Boston at 10:24 a.m.
Answer:
20
Step-by-step explanation:
Since it is the middle number of the data set
In all the answers we are solving for x. That means x needs to be by itself.
2x + 4a = 10
Subtract 4a.
2x = 10 - 4a
Divide by 2.
x = 5 - 2a
Answer is....
D. x=5-2a
