Answer 1

@welshfella do you know the answer?

Answer 2

the general form of the slope/intercpt equation is

y = mx + b

where m = slope and b = y-intercept

compare each of the options with this equation to give you the right one

Answer 3

for example if i had an equation with slope 3 and intercept - 4
its equation would be
y = 3x - 4

Answer 4

B?
