y=6x-4
x_1=1rArry_1=6*1-4=2
x_2=2rArry_2=6*2-4=8
graph{y=6x-4 [-10, 10, -5, 5]}

"see explanation"

Explanation:

"to find the intercepts, that is where the graph crosses"
"the x and y axes"

• " let x = 0, in the equation for y-intercept"

• " let y =0, in the equation for x-intercept"

x=0rArr0-y=4rArry=-4larrcolor(red)"y-intercept"

y=0rArr6x-0=4rArrx=4/6=2/3larrcolor(red)"x-intercept"

"plot the points "(0,-4)" and "(2/3,0)

"and draw a straight line through them for graph"
graph{(y-6x+4)((x-0)^2+(y+4)^2-0.04)((x-2/3)^2+(y-0)^2-0.04)=0 [-14.24, 14.23, -7.12, 7.12]}
