Write the equation for the line that goes through point (12, 15) with slope m = -2​

Y=5\4x

Step-by-step explanation:

gradient is given by ∆y/∆x

g=5/4

Y=MX+C

15=5/4(12)+c

15=15+c

C=0

y=mx+c

y=5\4x

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
