In this case:
m = 7 , x = - 3 , y = 4
Point-slope form of a line:
y = m ∙ x + b
Replace m = 7 , x = - 3 , y = 4 in this equation.
4 = 7 ∙ ( - 3 ) + b
4 = - 21 + b
Add 21 to both sides
25 = b
b = 25
y = m ∙ x + b
y = 7 x + 25
Hi beautiful people! i need help with a question.
Write the equation in point-slope form of a line that goes through (-3,4) with slope 7.
can someone pls help me out.

Ohhh, thank you very much that helped me.
point-slope form
the line through (h,k) with slope m is
y-k = m(x-h)
So your line is
y-4 = 7(x+3)
the line through (h,k) with slope m is
y-k = m(x-h)
So your line is
y-4 = 7(x+3)
