12-3=9 they switch up and it still equals the same thing
Answer: The slope of the line is 15 and y-intercept is 12.
Step-by-step explanation: We are given to find the slope and y-intercept of the straight line defined by the points (3, 57) and (5, 87).
We know that
the slope of a line passing through the points (3, 57) and (5, 87) is given by
Since the straight line passes through the point (3, 57), so its equation will be
So, the required equation of the straight line is 
Thus, the slope of the line is 15 and y-intercept is 12.
Y + 4x < 8
y < -4x + 8
2 points that satisfy this are (0,8) and (2,0)....and those happen to be ur x and y intercepts (where the line crosses the x and y axis)
graph...so go ahead and plot ur x and y intercepts (0,8) and (2,0).....ur slope is - 4.....so start at ur y int (0,8) and go down 4 spaces, and to the right 1...plot that point, then go down 4 spaces and to the right 1, then plot that point...keep doing this and u will have ur line...u should have crossed the x axis at (0,2)......ur line will be a dashed line since the problem has no equal sign.... the shading will go below the line because it is less then.
y - 3 > = 1/2x
y > = 1/2x + 3
2 points that satisfy this are : (0,3) and (-6,0)...ur x and y intercepts
graph : plot ur intercepts (0,3) and (-6,0)....u have a slope of 1/2...so start at ur x intercept (-6,0) and go up 1 space, and to the right 2 spaces, plot that point...then go up 1 and to the right 2, plot that point...keep doing this and u will cross the y axis at (0,3)....this line will be a solid line....the shading will go above the line.
Answer:
1. Make a table
2. Combine numbers
Step-by-step explanation:
First what you need to do is make a table making 2 columns, then name them tens and one. Put the tens place in the tens column and put the ones place in the ones column. Then, put all the numbers mentioned (16, 35, 24, 14) in the table and add the tens then add the ones!
Another strategy you can use is combining numbers. With 35 and 16 you can combine them to make 51. Then combine 24 and 14 to make 38. Then you add 51 and 38 to get 89.
I hope this helped your homework!
