Question

Write the slope-intercept equation for the line with slope 1/2 and y-intercept (0, -5)

Answer 1

sorry, was on phone.
This one?

Answer 2

yes and no problem

Answer 3

Ok, so slope intercept form is
Y = m*x + b

m is the slope
b is the y intercept

So for your problem, the slope = m = 1/2
and the y intercept is b = -5

then put into the equation
Y = (1/2)*x + (-5)

Y=(1/2)*x - 5

Answer 4

works ok?

Answer 5

so does this have an = in it or do i leave it like that

Answer 6

Y = (1/2)*x - 5
Yes, this has a = sign

Answer 7

i see that i have to graph the line as well

Answer 8

ok. so plot the point (0,-5)

Answer 9

Then count up one square and to the right two squares and draw another point. connect the dots.

Answer 10

and draw a line extending beyond the dots too. you can keep counting up one, to the right two places

Answer 11

nice drawing

Answer 12

Y = (1/2)*x - 5
if y = 0, solve for x for another point:
0 = (1/2)*x-5
5=(1/2)*x
x=10
so you can plot the point (10,0) also

Answer 13

so i can plot both or either or?
