Answer:
Once your equation is in slope-intercept form: "y = mx+b", the coefficient of "x" (the "m") is the slope. The constant (the "b") is the y-intercept at (0, b).
Step-by-step explanation:
Answer:
B) -7
Step-by-step explanation:
x+y
8+(-15)=8-15=-7
Step-by-step explanation:
If it's a straight line the use formula
m= gradient of line
c = y-intercept
we know that y-intercept is 4 so coordinate is
(0,4)
Equation also passes (2,10)
Use both coordinate to find gradient
m= vertical distance / horizontal distance
= (10-4) / (2-0)
= 3
y = 3x + 4
Answer:
24/4/-a+12=/9d
Step-by-step explanation:
7/5 = 14/10 = 28/20
Numerator = x
Denominator = x-4
Add 3 to both:
x +3 / (x-4+3)
x+3 = 14
(x-4 +3) = 10 = x-1 = 10
x = 11
Check:
11 -4 = 7 ( denominator is 4 less than the numerator.)
add 3 to both:
11+3 = 14
7+3 = 10
14/10 reduces to 7/5
The original fraction would be 11/7
