Good morning! So, what this question wants us to do is find each y value given its x value. Without the function it gives us already, this would be pretty difficult. It gives us a function rule of y=2x+3. This means that we need to plug in each x value into the equation and solve for y. Let’s work on these first three.
y=2x+3} x=-4 y=2(-4)+3 y=-8+3 y=-5 So, if x=-4, then y=-5.
y=2x+3} x=-2 y=2(-2)+3 y=-4+3 y=-1 So, if x=-4, then y=-1.
y=2x+3} x=0 y=2(0)+3 y=0+3 y=3 So, if x=0, then y=3.
Try out the last one, and if you have any questions, comment below! Here are some extra x values if you need more practice. Using the same function rule, y=2x+3, try to find the y value if x=-6, x=-3, x=5, or x=6.
To find the value you have to know how many hours the repairman took to repair. Then after you find how many hours he took multiply the hours by 35 than add 25.
