his score was increased... so if he is now at 67 and it was increased by 7 so his first grade would have been 60.
For any y-intercept, the x-coordinate is zero. This is something to bear in mind to start with.
Now to find the y-intercept, find g(0) = -2.
Therefore the answer is (0,-2)
17 + 5shirts = 42
5shirts = 42-17 = 25
1shirt = 25/5 = 5
A shirt costs £5.
3*5 + 1hat = 17
15 + 1hat = 17
1hat = 2
A hat costs £2
Plug y=-4x+5 into a website called desmos, it will give you a graph! The y-intercept is 5 and it’s at a slope of 4/1
I dont completely know but it might be 3
