Question

what is the slope-intercept form of the linear equation whose graph passes through (-2,4) and is parallel to the graph 3x+y=6?

a) y =-3x - 2
b) y =-3x + 10
c) y = 3x - 2
d) y = 3x + 10


which linear equation represents a line that passes through (3,-7) and has a slope of -4?

a) y = -4x-19
b) y = -4x-5
c) y = -4x+5
d) y = -4x+19

Answer 1

what is the slope of the line
y = -3 x + 6
?

using that slope:
(y - 4) / (x + 2)= slope
solve for y
=================================
y = -4 x + b
-7 = -4(3) + b
b = 5
so
y = -4 x + 5

You absolutely have to be able to do these - practice !!!!!!
