Answer:

d)87

Explanation:

let's find the slope first


m = (y _(2) -y_1)/(x_2 -x_1)


m = (5 - 3)/(2 - 1)


m = 2

let's find y-intercept

according to the question

3=1.2+b

3=2+b

therefore

b=1

so the equation is

y=2x+1

given

x=43

therefore

y=43.2+1

y=86+1

y=87

the equation is y=2x+1 so plug in 43 for y
43=2x+1
42=2x
21=x!!
