You are given
two points, (-1, 10) and (5, 8). You are required to find the equation in slope
intercept form given the points. The equation of a slope intercept form is y =
mx + b. Where m is the slope and b is the y-intercept. By definition, slope, m,
is the rise over run or the difference of y over the difference of x.
m =
y2-y1/x2-x1
Let us denote
y2=8, y1=10, x2=5 and x1=-1 and we get
m =
8-10/5-(-1)
<span><u>m = -1/3</u>,
a negative slope means it is rising to the left of the graph.</span>
Since the
slope passes the two points, it also passes the y-intercept. Choose one of the
points, (-1, 10) and substitute it to y = mx + b.
y = mx + b
10 =
(-1/3)(-1) + b
<u>b = 29/3</u>
<u>The
equation now is y = -1/3x + 29/3.</u>
Answer:
150
Step-by-step explanation:
159 rounded to the nearest tenth is 160
160-10=150
Step-by-step explanation:
we have two lines you have to draw.
one is all in the bottom left quadrant (for x<=0) and one in the upper right quadrant (for x>5).
the easiest is for x>5. the line function is only
f(x) = y = 3
so, this is a horizontal line on the grid line for y = 3. it starts above x=5 and then goes all the way to the right ("to infinity and beyond !"). just, if possible, mark the starting point at x=5 as a little empty "circle" instead of a full dot, as x=5 is explicitly excluded (due to x>5).
and for x<=0 the line
f(x) = y = 4x - 3
goes sharp down but goes a little bit to the left the further down it goes. it starts with x=0, which gives y=-3 per the function.
so, the starting point (with a full dot, as x=0 is included) is (0,-3).
from there it goes sharp down and a little bit to the left.
for example the next point is for x=-1, which gives y=-7, so it is the point (-1,-7). x=-2 gives y=-11 and the point (-2,-11).
the line has to go through so these points and further down (again, "to infinity and beyond !"), as to move further left on the negative x-axis.
