Answer 1

Graph B.

Since the slope is negative, the line goes down and to the right. The line in graph B intercepts the y-axis at 1, which it should according to this equation.

Answer 2

This equation fits the y=mx+b model. Where m=slope and b=y intercept. When x=0, y=0+1. This gives you a point on the graph. m=slope which is change in y over change in x. In this problem start at (0,1), the y-intercept. Then go down 3 (down because of the negative sign) then to the right to 2. This gives you another point on the graph. Connect the dots and extend beyond the plotted points.

If the slope had been positive then you go up then to the right.

Another way to get a second point is to let y=0. In this case
0=-3/2x+1
3/2x=1
x=2/3

If you plot the first point (0,1) then (2/3,0) the line will go through point plotted by using the slope.

Answer 3

Draw out a table with x and y % numbers for x. Ex: a million, 2, 3. placed them on your table on the x column. Then interior the equation y=2x+5 plug in those numbers that you chosen for x and clean up the equation. Ex: y=2(a million)+5 y=2+5 y=7 so on the y column placed the 7 next to the a million. this can properly be your first set of numbers to graph. (a million,7) next one: Do the similar apart from plug interior the subsequent x huge kind for x interior the equation. y=2(2)+5 y=4+5 y=9 next one: y=2(3)+5 y=6+5 y=11 table is below. x | y a million | 7 2 | 9 3 | 11 Now graph the coordinates. (a million,7) , (2,9) , (3,11) on graph paper. come across the a million on the x-axis and then from there pass up 7 on the y-axis. it really is your first dot. come across 2 on the x-axis and then from there pass up 9 on the y-axis. it really is your second dot. come across 3 on the x-axis and then from there pass up 11 on the y-axis. Thi sis your 0.33 dot. Now connect the dots. it really is your graph.

Answer 4

The correct answer is A

This equation is in the slope-intercept form (y = mx + b), where whatever accompanies the x ("m" in the example equation) represents the slope. In this case the slope is negative meaning that it should go "downward" and the last number ("b" in the example equation) is the y intercept or the point in which the line crosses the y axis, which is 1 in this case.

HOPE THIS HELPS!

Answer 5

sure:

x=0, y=1 (y intercept)

y=0, x=-1/(-3/2)= -1*-2/3=2/3

x intercept=2/3, or .666.

Connect the dots

Answer 6

The line has a negative slope and goes through (0,1)

=========> Answer is b

Answer 7

It's either A or B. I can't tell because the pictures are too small. It's whichever one crosses the y-axis at 1.

Good luck!
