So i'm not going to be able to help you with all of these.
00:03
When you submit problems, you're only supposed to submit like one or two, not an entire worksheet.
00:09
So i'll do number one, using two points.
00:13
It wants you to graph the equations given the following details.
00:18
So 2, negative 1, and 3, 2 is this graph right here.
00:29
And i don't have access for a ruler, but that's what the line is going to look like.
00:35
And if you're looking for the equation of the line, this is going up three, so down three, so the dot should have been here, down three.
00:46
So my equation of my line should have been, for this one, y equals 3x minus 7.
00:56
Okay, i'll do one more.
01:00
I'll do this one.
01:03
4 .3, so over 4, up 3, 1, 2, 3, and 0, 5, so 0, 5.
01:13
And it's a negative slope.
01:18
And my equation would be y equals, and i'm just going to go down to, so down to 1, 2, 3, 4.
01:27
So it actually is 1⁄2 because if i simplify 2 4, so 1⁄2 ,000, x plus 5.
01:34
Five but it's a negative slope okay all right find the slope of each line describe the graph using the intercepts so i'll do five and seven so for five i have my x and y so zero negative three and one and zero so i'm going up three and up one so it would be three over 1 and my y intercept is negative 3 so my equation would be y equals 3x minus 3 for number 7 it's 5 0 in 0 negative 4 and i'm going down 4 down 5 so be 4 over 5 and my y intercept is negative 4 so my equation would be y equals 4 5x minus 4...
