Question

Y= 6x + 13 y= 4x + 7

Answer 1

The first one is 0 and the second one is the same

Answer 2

Solution 1: y = 6x - 13
Solution 2: y = 4x - 7

Graphic organizers
-6(x) + (y) = 13
-4(x) + (y) = 7

y-intercept in solution 2
 y = 4(x) + 7

y-intercept in solution 1
4(x)+7 - 6(x) = 13  
-2(x) = 6

We didn't find the y-intercept just yet , so we can look for the x-intercept

x-intercept in solution 1
2(x) = -6   
x = -3 

y = 4(-3) + 7 = -5

Your x-intercept: -3
Your y-intercept: -5

Therefore your answer would have to be
{-3, -5}
