Write an equation in point-slope form of the line through point J(4, 2) with slope 3.
1 answer:
Point slope form is:
y − y
= m(x − x)
Where x and y are two known coordinates and m is the slope.
Substitute (4,2) as x and y and 3 as m to find the point-slope form.
<span>y − 2 = 3(x − 4)
</span>
Taking it to the next step would be to turn this into slope-intercept form, y=mx+b
<span>y − 2 = 3(x − 4)
y</span> − 2 = 3x − 12
y = 3x − 10
y − y
Where x
Substitute (4,2) as x and y and 3 as m to find the point-slope form.
<span>y − 2 = 3(x − 4)
</span>
Taking it to the next step would be to turn this into slope-intercept form, y=mx+b
<span>y − 2 = 3(x − 4)
y</span> − 2 = 3x − 12
y = 3x − 10
