Answer:
(x, y) = (1, 8)
Step-by-step explanation:
A graphing calculator quickly tells you the point of intersection.
__
You can equate the y-values and solve for x.
3x +5 = -2x +10
5x = 5 . . . . . . . . . add 2x-5
x = 1 . . . . . . . divide by 5
3·1 +5 = y = 8 . . . . substitute for x in the first equation
The point of intersection is (x, y) = (1, 8).
Answer:
a. What is the slope of the line?
b. What is the x-intercept of the line? (Where does the line cross the x-axis?)
c. What is the y-intercept of the line? (Where does the line cross the y-axis?)
Step-by-step explanation:
Calculate slope:
