Question

Given the point (4, 5) and the slope of 6, find y when x = 24. 118 144 125 149

Answer 1

y = mx + b
5 = 6(4) + b
b = -19
equation
y = 6x - 19
when x = 24,
y = 6(24) - 19 = 125

answer
125

Answer 2

Answer: y=125

Explanation:

We know that the equation of a line with slope 'm' and passing through point (a,b) is given by :-

`(y-b)=m(x-a)`

Thus, the equation of a line with slope 6 and passing through point (4,5) with is given by :-

`(y-5)=6(x-4)`

Substitute x=4, we get

`(y-5)=6(24-4)\\\\\Rightarrow(y-5)=6(20)\\\\\Rightarrow(y-5)=120\\\\\Rightarrow y=125`
