Question

Write an equation of a line that passes through the point (0, 4) and whose slope is 4. 
A.   y = x + 4  
B.   y = 4x + 4  
C.   y = x – 4  
D.   y = x

Equation of a line with slope and one point is given by:

$$\large \color{green}{(y-y_1) = m(x-x_1)}$$

EQUATION OF THE LINE, MEMORIZE!!!!
y = mx+b

m = slope
b = y-intercept

we know slope so just plug into equation with the point

anonymous · Answer

Here m = 4 and $x_1 = 0$, $y_1 = 4$

australopithecus · Answer

so we have

y = 4x + b

solve for b by subbing in the point into the equation,

(0,4)

remember,

(x, y)

anonymous · Answer

y=4x+ 4?
