M is the slope (rise over run). b is the Y-intercept (on the y axis). plot the y point then use your slope to find the line

So we can just set up a proportion

14.5/2=x/3

we can cross multiply

so that means

2x=43.5

x=21.75

Good afternoon/evening.

-4^4 = four to the fourth power = (-4)(-4)(-4)(-4) = 256
Remember, when a negative is multiplied by a negative it equals a positive.

Can someone help with this problem please? Thanks.
Zarrin [17]
First, find the slope of the line. Use the two points given, (-4,0) and (4,2), in the slope formula rise over run. The change in rise is 2 and the change in run is 8, meaning that the slope is 2/8, simplified to 1/4. The y-intercept is 1, shown by the graph and the dashed line and shaded area means that the inequality symbol must be <. Slope-intercept form is shown as y = mx + b, so after putting our information in to the equation the answer is y < 1/4x + 1. Hope this helps!
