hi, if u can't see the photo clearly,
for first qn, gradient is -2/5. recall that gradient = m so rearrange the equation to be in y=mx+c format.
for second qn, for the line, y-intercept is -3 and x passes through 1.5. draw your line to cross the line that's already on the graph.
when u find the point at which the two lines cross, check the x and y values
