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
1. x=5/2
2. x=3/4-3/4y
y belongs R
Answer:
Step-by-step explanation:
2,57 divided by 1.5 equals
1.713
a. 3^4 which is equal to (3^-3)(3^7)
