Describe how to graph a line given an equation in slope-intercept form.

An equation in slope intercept form is written as y=mx+b
m is the slope of the line
b is the y intercept or the point which the line crosses the y-axis

so as long you have the m and the b of the equation you can graph it.

for example say you were given the equation y=3x+7
plot a point at (0,7) as your y-intercept because b=7
then from that point go up the line 3 units and over one and plot a point. the slope was 3, so that's up three over 1 (only go over one because 3 is the same as 3/1. the numerator tells you how many units to go up. the denominator tells you how many to go down.)

so continue going up three over one until you have enough points to draw your line.

I hope this helped!!

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
