Question

A pair of equations is shown below:

Answer 1

Eay peasy

solve graphically
graph them and find the poitn that they intersect at

y=mx+b
m=slope
b= y intercept

y=7x-9
slope=7
yintercept=-9

y=3x-1
slope=3
yinercept=-1

I have attached graph below


easier way would be to simply sub them and solve
7x-9=y=3x-1
7x-9=3x-1
4x-9=-1
4x=8
x=2

y=3x-1
y=3*2-1
y=6-1
y=5
(2,5) is solution

Answer 2

Answer:

A) We need to put them on a graph to see where the points intersect.

So in y = MX = b, The m is slope and b is the y-intercept. So in y = 7x − 9 seven is the slope and 9 is the y-intercept. And in y = 3x − 1 Three is the slope and 1 is the y-intercept.

B) 2,5 is were these lines intersect.
