Gradient of line= (y2-y1)/(x2-x1)
Gradient of line= (10-(-6))/(8-4)
Gradient of line= 16/4
Gradient of line= 4
Y-intercept
Y=4x+c
When x=8, y=10
10=32+c
c= -22
Equation of line
Y=4x-22
When x=b, y=2b
Y=4x-22
2b=4b-22
22=2b
b=11
7miles---------1hr
11.2miles------- x
cross multiply;
11.2 × 1 = 7 × x
x= 11.2÷7
x=1.6hr
Ok ima try
a x 3 + c x 2 = 14
This is how I learned please don’t roast me if I do it wrong
180 cm goodluck and keep your head up!
There's an equation to find the length between 2 points on a plane.
√[(2-4)2 + (2-7)2] = √29
√[(4-6)2 + (7-2)2] = √29
√[(2-6)2 + (2-2)2] = 4
Therefore, Triangle ABC is an iscoceles triangle!
