Answer:
(3, 0) and (5, 0)
Step-by-step explanation:
we have

we know that
The x-intercepts are the values of x when the value of y is equal to zero
so
For y=0

The formula to solve a quadratic equation of the form
is equal to

in this problem we have
so

substitute in the formula





so
x=3, x=5
therefore
The x-intercepts are (3,0) and (5,0)
Well I don't know if you are looking for the variable but here it is :)
Well according to the slope intercept equation.
Y = mx +/- b
The slope is the value m
The y intercept is b
To graph the function, one sure way to do it is simply make a table of values picking any x values that fall within the graph space, and finding out the resulting y values and using the points to graph.
For instance for the first graph, if x = 0, y = 5, that is one possible point. Keep on choosing x values to graph.
2x + y = 10
5x - y = 18
7x = 28
x = 4
2(4) + y = 10
8 + y = 10
y = 2
(4,2)
