Explanation:
#"the equation of a line in "color(blue)"slope-intercept form"# is.
#•color(white)(x)y=mx+b#
#"where m is the slope and b the y-intercept"#
#y=3/4x-4" is in this form"#
#"with slope "=3/4" and y-intercept "=-4#
#"Since "m>0" line slopes upwards from left to right"#
#"from "(0,-4)" go 3 up and 4 right "to(4,-1)#
#"Plot the points "(0,-4)" and "(4,-1)#
#"Draw a straight line through them for graph"#
graph{(y-3/4x+4)((x-0)^2+(y+4)^2-0.04)((x-4)^2+(y+1)^2-0.04)=0 [-10, 10, -5, 5]}
