Well you would have to use the formula x= -b/2a to find the value of x and then substitute that value of x in the equation to find y<span />
Answer:
A
Step-by-step explanation:
They have the same slope but their y-intercepts are different (they are crossing the y-axis at different points).
Answer:
5
Step-by-step explanation:
The equation of a straight line is :
y=mx+c
where m is the gradient and c is the y-intercept
so if m equals 5 then the gradient is 5
1. 81 1/2 = 163/2
2. 32 1/5 - 64 1/3 =
483/15 - 965/15 =
-482/15 or -32 2/15
3. 16 1/4 = 65/4
4. 49 1/2 + 27 1/3 =
99/2 + 82/3 =
297/6 + 164/6 =
461/6 or 76 5/6
