Step-by-step explanation:
to find the intercepts, that is where the line crosses the x and y axes
• let x = 0, in the equation for the y-intercept
• let y = 0, in the equation for x-intercept
x = 0
⇒ - 5 = 4y ( divide both sides by 4 )
y = - ← y- intercept
y = 0
7x - 5 = - 6x ( add 6x to both sides )
13x - 5 = 0 ( add 5 to both sides )
13x = 5 ( divide both sides by 13 )
x = ← x- intercept
