#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]}

Answer:

#"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]}
