Question

Given the two equations:

y + x = 5
-2x = -1
0) Draw the graphs of both equations on the same pair of axes by using a scale of 1cm to
represent 1 unit on both axes.

Use your graph to determine the point of intersection.
​

Answer 1

Explanation:

I can draw graphs on the application

eq1) is a line through y = 5 with a negative slope of -1 y = -x + 5

eq2) is a vertical line at x = 1/2 NO y intercept or slope

-2x = -1 ---> x = -1/-2 = 1/2

They intersect at

y = -x + 5 and x = 1/2 Substitute x=1/2 into

y = -1/2 + 5

y = 4.5

intersect at (1/2, 4.5)
