Question

Draw the graphs of the lines below on the same grid to find the coordinates of the point of intersection. y=3x+8 3x+y=2

Answer 1

Explanation:

y = 3x + 8

y = -3x + 2

the y intercept tells you where it hits y on the graph

the red hit 8

the blue hits 2

the slope (3x or -3x) means it goes up/down 3 and over 1

rise over run

3/1 = 3

ex. 2/5

up 2 over 5

ex. 4

up 4 over 1
