The slope of a line is ½ and the y-intercept is 4. Which choice is the x-intercept of this line? [1] -8 [2] 8 [3] -4 [4] 4

i think c. but don't trust it.

step-by-step explanation:

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
