Answer:
y=3x-1
Step-by-step explanation:
you first find the gradient
(-7,-5). (-7,-2)
x¹ y¹ x² y²
gradient=y²-y¹
x²-x¹
-2+5
-7+7
3/1=3. gradient is 3
equation formula= y=mx+c
(among the two sets of value you were given use one eg I will use -7 and -2)
y-(-7)/x-(-2)=3
y+7/x+2=3
y+7=3(x+2)
y+7=3x+6
y=3x+6-7
y=3x-1
