Which equation in slope intercept form contains the point (4, -1) and has a slope of 3

Nimfa-mama [501]

Answer:

Final answer is $y=3x-13$ .

Step-by-step explanation:

Given that slope of the line is m=3

Plug the given point (4,-1) and the slope m=3 into point sloep formula:

$y-y_1=m\left(x-x_1\right)$

$y-(-1)=3\left(x-4\right)$

$y+1=3\left(x-4\right)$

$y+1=3x-12$

$y=3x-12-1$

$y=3x-13$

Which looks like slope intercept form of line y=mx+b

Hence final answer is $y=3x-13$ .
